A structural study confirms that the sample is a single phase. Magnetic measurements show that the sample is a charge ordered Manganite. The sample undergoes two successive magnetic phase transitions with the variation of temperature: a charge ordering transition occurred at TCO = 212 K followed by a Paramagnetic (PM) to ferromagnetic (FM) transition around TC = 115 K. From an electrical point of view, a saturation region was marked in the conductivity as a function of Temperature s(T) curves at a specific temperature. The dc-conductivity (sdc) reaches a maximum value at 240 K. The obtained results are in good agreement with the temperature dependence of the average normalized change (ANC). We found that the conduction mechanism was governed by small polaron hopping (SPH) in the high-temperature region and by variable range hopping (VRH) in the low-temperature region. Complex impedance analysis indicates the presence of a non-Debye relaxation phenomenon in the system. Also, the compound was modeled by an electrical equivalent circuit. Then, the contribution of the grain boundary in the transport properties was confirmed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=manganites" title="manganites">manganites</a>, <a href="https://publications.waset.org/abstracts/search?q=preparation%20methods" title=" preparation methods"> preparation methods</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetization" title=" magnetization"> magnetization</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetocaloric%20effect" title=" magnetocaloric effect"> magnetocaloric effect</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20and%20dielectric" title=" electrical and dielectric"> electrical and dielectric</a> </p> <a href="https://publications.waset.org/abstracts/142916/structural-magnetic-electrical-and-dielectric-properties-of-pr08na02mno3-manganite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142916.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Two-Dimensional Electron Gas with 100% Spin- Polarization in the (LaMnO3)2/(SrTiO3)2 Superlattice under Uniaxial Strain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiwuer%20Jilili">Jiwuer Jilili</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrizio%20Cossu"> Fabrizio Cossu</a>, <a href="https://publications.waset.org/abstracts/search?q=Udo%20Schwingenschlogl"> Udo Schwingenschlogl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By first-principles calculations we investigate the structural, electronic, and magnetic properties of the (LaMnO3)2/(SrTiO3)2 superlattice.

By applying moderate bias currents (~ 10 mA), it is found that Joule self-heating simply gives rise to a temperature deviation between the thermostat and the test sample, but the intrinsic ρ(T) relationship measured at a low current (0.1 mA) changes little. However, it is noteworthy that the low-temperature transport behavior degrades from metallic to insulating state after applying higher bias currents ( > 31 mA) in a vacuum. Furthermore, metallic transport can be recovered by placing the degraded film in air. The results clearly suggest that the oxygen vacancy in the La₀.₈Ba₀.₂MnO₃ films is controllable in different atmospheres, particularly with the aid of the Joule self-heating. According to the SEM images, we attribute the controlled oxygen vacancy to the nano-sized labyrinth pattern of the films, where the large surface-to-volume ratio plays a curial role. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=controlling%20oxygen%20vacancy" title="controlling oxygen vacancy">controlling oxygen vacancy</a>, <a href="https://publications.waset.org/abstracts/search?q=joule%20self-heating" title=" joule self-heating"> joule self-heating</a>, <a href="https://publications.waset.org/abstracts/search?q=manganite" title=" manganite"> manganite</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel%20method" title=" sol-gel method"> sol-gel method</a> </p> <a href="https://publications.waset.org/abstracts/118376/joule-self-heating-effects-and-controlling-oxygen-vacancy-in-la08ba02mno3-ultrathin-films-with-nano-sized-labyrinth-morphology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118376.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Nature of Polaronic Hopping Conduction Mechanism in Polycrystalline and Nanocrystalline Gd0.5Sr0.5MnO3 Compounds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soma%20Chatterjee">Soma Chatterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=I.%20Das"> I.

The variation of transport properties is modified by tuning the grain size of the material. In the high-temperature semiconducting region, temperature-dependent resistivity data can be well explained by the non-adiabatic small polaron hopping (SPH) mechanism. In addition, the resistivity data for all compounds in the low-temperature paramagnetic region can also be well explained by the variable range hopping (VRH) model. The parameters obtained from SPH and VRH mechanisms are found to be reasonable. In the case of nanocrystalline compounds, there is an overlapping temperature range where both SPH and VRH models are valid simultaneously, and a new conduction mechanism - variable range hopping of small polaron s(VR-SPH) is satisfactorily valid for the whole temperature range of these compounds. However, for the polycrystalline compound, the overlapping temperature region between VRH and SPH models does not exist and the VR-SPH mechanism is not valid here. Thus, polarons play a leading role in selecting different conduction mechanisms in different temperature ranges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20resistivity" title="electrical resistivity">electrical resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=manganite" title=" manganite"> manganite</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20polaron%20hopping" title=" small polaron hopping"> small polaron hopping</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20range%20hopping" title=" variable range hopping"> variable range hopping</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20range%20of%20small%20polaron%20hopping" title=" variable range of small polaron hopping"> variable range of small polaron hopping</a> </p> <a href="https://publications.waset.org/abstracts/166291/nature-of-polaronic-hopping-conduction-mechanism-in-polycrystalline-and-nanocrystalline-gd05sr05mno3-compounds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166291.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Preparation and Conductivity Measurements of LSM/YSZ Composite Solid Oxide Electrolysis Cell Anode Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20C.%20Vaso">Christian C.

To increase the ionic conductivity or diffusion of ions through the anode, Yttria-stabilized Zirconia (YSZ), which has good ionic conductivity, is proposed to be combined with LSM to create a composite electrode and to obtain a high mixed ionic and electronic conducting anode. In this study, composite of lanthanum strontium manganite and YSZ oxide, La<sub>0.8</sub>Sr<sub>0.2</sub>MnO<sub>3</sub>/Zr<sub>0.92</sub>Y<sub>0.08</sub>O<sub>2</sub> (LSM/YSZ), with different wt.% compositions of LSM and YSZ were synthesized using solid-state reaction.

Surface morphology of the samples via SEM analysis revealed a well-sintered and densified pure LSM, while a more porous composite sample of LSM/YSZ was obtained.

The samples were synthesized by auto-combustion Sol-Gel method. The phase purity, crystallinity, and the structural properties for all prepared samples were examined by X-ray diffraction. XRD refinement indicates that the samples are crystallized in the orthorhombic single-phase with Pnma space group. Temperature dependence of magnetization measurements under a magnetic applied field of 0.02 T reveals that the samples with (x=0.0, 0.1, 0.2 and 0.3) exhibit a paramagnetic (PM) to ferromagnetic (FM) transition with decreasing temperature. The Curie temperature decreased with increasing Fe content from 256 K for x =0.0 to 80 K for x =0.3 due to increasing of antiferromagnetic superexchange (SE) interaction coupling. Moreover, the magnetization as a function of applied magnetic field (M-H) curves was measured at 2 K, and 300 K. the results of such measurements confirm the temperature dependence of magnetization measurements. The magnetic entropy change|∆SM | was evaluated using Maxwell's relation. The maximum values of the magnetic entropy change |-∆SMax |for x=0.0, 0.1, 0.2, 0.3 are found to be 15.35, 5.13, 3.36, 1.08 J/kg.K for an applied magnetic field of 9 T.

At pure states, LSM exhibited a high electronic conductivity while YSZ demonstrated an ionic conductivity of 3.25 x 10-4 S/cm at 700 °C under Oxygen gas environment with calculated activation energy of 0.85eV. The composite samples were also studied and revealed that as the YSZ content of the composite electrode increases, the total conductivity decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic%20composites" title="ceramic composites">ceramic composites</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cells" title=" fuel cells"> fuel cells</a>, <a href="https://publications.waset.org/abstracts/search?q=strontium%20lanthanum%20manganite" title=" strontium lanthanum manganite"> strontium lanthanum manganite</a>, <a href="https://publications.waset.org/abstracts/search?q=yttria%20partially-stabilized%20zirconia" title=" yttria partially-stabilized zirconia"> yttria partially-stabilized zirconia</a> </p> <a href="https://publications.waset.org/abstracts/50152/development-of-lsmysz-composite-anode-materials-for-solid-oxide-electrolysis-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50152.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">312</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Optimal Sputtering Conditions for Nickel-Cermet Anodes in Intermediate Temperature Solid Oxide Fuel Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Hassan%20Tanveer">Waqas Hassan Tanveer</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoon%20Ho%20Lee"> Yoon Ho Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Taehyun%20Park"> Taehyun Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Wonjong%20Yu"> Wonjong Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaegeun%20Lee"> Yaegeun Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusung%20Kim"> Yusung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Suk%20Won%20Cha"> Suk Won Cha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nickel-Gadolinium Doped Ceria (Ni-GDC) cermet anodic thin films were prepared on Scandia Stabilized Zirconia (ScSZ) electrolyte supports by radio frequency (RF) sputtering, with a range of different sputtering powers (50 – 200W) and background Ar gas pressures (30 – 90mTorr). The effects of varying sputtering power and pressure on the properties of Ni-GDC films were studied using Focused Ion Beam (FIB), X-ray Photoelectron Spectroscopy (XPS), X-ray Diffraction (XRD), Energy Dispersive X-ray (EDX), and Atomic Force Microscopy (AFM) techniques. The Ni content was found to be always higher than the Ce content, at all sputtering conditions. This increased Ni content was attributed to significantly higher energy transfer efficiency of Ni ions as compared to Ce ions with Ar background sputtering gas. The solid oxide fuel cell configuration was completed by using lanthanum strontium manganite (LSM/YSZ) cathodes on the other side of ScSZ supports. Performance comparison of cells was done by Voltage-Current-Power (VIP) curves, while the resistances of various cell components were observed by nyquist plots. Initial results showed that anode films made by higher powered RF sputtering performed better than lower powered ones for a specific Ar pressure. Interestingly, however, anodes made at highest power and pressure, were not the ones that showed the maximum power output at an intermediate solid oxide fuel cell temperature of 800°C. Finally, an optimal sputtering condition was reported for high performance Ni-GDC anodes. <p class="card-text"><strong>Keywords:</strong> <a
