magnetoelectric antennas integrated on thin-film bulk acoustic wave resonators. The effects of losses in piezoelectric and magnetostrictive materials on radiation efficiency are analyzed. Results show that mechanical quality factor and piezomagnetic stress constant are key parameters, and eddy current loss is related to the thickness of the magnetostrictive layer.

However, the relevant research is still exploratory, and the antenna's multi-field coupling modeling and performance analysis are imperfect. This work presents a cellular model based on finite element simulation to analyze the radiation characteristics of the ME antenna integrated on a thin-film bulk wave resonator (FBAR). Compared with the finite difference time domain (FDTD) method, the cellular model has the advantages of simplicity and high universality. The effects of mechanical and dielectric losses of piezoelectric (PE) material and mechanical and eddy current losses of magnetostrictive (MS) material on radiation efficiency are analyzed through the intensive research of unit cells of four different material combinations. Results show that the mechanical quality factors and piezomagnetic stress constant are the key parameters to determine the radiation efficiency. Besides conductivity and permeability, eddy current loss is also closely related to the thickness of the MS layer.

<strong>Summary:</strong> A study on collecting the energy of low-frequency and low-speed impact vibration to power microelectronic devices is conducted, and a new piezoelectric-electromagnetic hybrid energy harvester is proposed. It can convert horizontal reciprocating rotational motion into vertical reciprocating motion, and the deformation of the flexural cantilever beam realizes piezoelectric energy harvesting. The rotation of the central cylinder causes the magnet-installed hollow tube to move up and down, generating electromagnetic induction with the coil in the housing, and achieving electromagnetic energy harvesting. The harvester has a single input of low-frequency or low-speed impact vibration and multiple outputs of energy harvesting. It is verified through theoretical modeling, simulation, and experiments that it can generate an output power of 120 mW under 2.5 Hz vibration excitation. </div> </div> <div class="d-flex justify-content-between"> <p class="font-weight-bold"> <span class="text-primary">JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS</span> (2025) </p> <div class="flex-shrink-0"> <a class="btn btn-outline-primary btn-sm" href="https://www.peeref.com/zh/works/85218499/add-to-collection" target="_blank"> <strong>添加到收藏夹</strong> </a> </div> </div> </div> <div class="my-4 border-bottom"> <div> <span class="d-inline-block badge badge-blue"> Article </span> <span class="d-inline-block badge badge-cyan"> Materials Science, Multidisciplinary </span> </div> <h4> <a href="https://www.peeref.com/zh/works/83029583" class="text-dark hover-underline">Analysis of braking performance and heat dissipation characteristics of multi-disc magnetorheological brake with an inner water-cooling mechanism</a> </h4> <p class="text-ellipsis-2">Jiawei Zhang, Guoliang Hu, Qian Cheng, Lifan Yu, Wencai Zhu</p> <div class="d-flex mb-3"> <div class="p-3 rounded bg-light-blue"> <strong>Summary:</strong> This paper presents a multi-disc MR brake with an inner water-cooling mechanism, which enhances the braking performance and heat dissipation by increasing the effective damping gaps and designing an inner water-cooling mechanism.

The results showed that a stable SAF skyrmion can be successfully generated when the track width and the distance between the current injection position and the left side of the track are larger than a certain threshold. A wider track leads to lower total energy and higher speed of the SAF skyrmion within a certain threshold, while a larger distance leads to lower total energy and velocity within another threshold. These results are useful for understanding SAF skyrmion physics and may provide guidance for nonvolatile computing devices. </div> </div> <div class="d-flex justify-content-between"> <p class="font-weight-bold"> <span class="text-primary">JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS</span> (2025) </p> <div class="flex-shrink-0"> <a class="btn btn-outline-primary btn-sm" href="https://www.peeref.com/zh/works/84464814/add-to-collection" target="_blank"> <strong>添加到收藏夹</strong> </a> </div> </div> </div> <div class="my-4 border-bottom"> <div> <span class="d-inline-block badge badge-blue"> Article </span> <span class="d-inline-block badge badge-cyan"> Materials Science, Multidisciplinary </span> </div> <h4> <a href="https://www.peeref.com/zh/works/83024634" class="text-dark hover-underline">Fast response of TMR magnetic sensor in high-frequency alternating magnetic fields under varying temperature conditions</a> </h4> <p class="text-ellipsis-2">Peng Chen, Jiafeng Feng, Yu Zhang, Yizhan Wang, Hui Huang, Shuaipeng Wang, Wenfeng Tian, Hui Deng, Caihua Wan, Hongxiang Wei, Wenrong Si, Anfeng Jiang, Xiufeng Han</p> <div class="d-flex mb-3"> <div class="p-3 rounded bg-light-blue"> <strong>Summary:</strong> The TMR magnetic sensor has many advantages, but there are challenges in generating high-frequency alternating magnetic fields.

It was found that the magnetic properties of the magnets in the as-built condition vary significantly, and heat treatment can significantly change the magnetic properties, and the response characteristics of the magnets depend on the build condition and the initial coercivity. The crystallization of amorphous phases in the microstructure is responsible for the improvement of magnetic properties. Exceeding the optimal heat treatment temperature leads to the precipitation of α-Fe and a decrease in coercivity, but an increase in remanence. Magnets with low initial coercivity require higher heat treatment temperatures to achieve optimal magnetic performance and show enhanced stability against overaging. </div> </div> <div class="d-flex justify-content-between"> <p class="font-weight-bold"> <span class="text-primary">JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS</span> (2024) </p> <div class="flex-shrink-0"> <a class="btn btn-outline-primary btn-sm" href="https://www.peeref.com/zh/works/83119625/add-to-collection" target="_blank"> <strong>添加到收藏夹</strong> </a> </div> </div> </div> <div class="my-4 "> <div> <span class="d-inline-block badge badge-blue"> Article </span> <span class="d-inline-block badge badge-cyan"> Materials Science, Multidisciplinary </span> </div> <h4> <a href="https://www.peeref.com/zh/works/83361703" class="text-dark hover-underline">Role of (Pr20Nd80)60Tb15Cu15Ga10 intergranular addition on the magnetic properties of Nd-Fe-B sintered magnet</a> </h4> <p class="text-ellipsis-2">Shaoqing Ren, Ke Lv, Han Li, Jihao Xie, Jiaying Jin, Mingjing Zhao, Quan Li, Yizhou Jiang, Zhongye Zhang, Mi Yan</p> <div class="d-flex mb-3"> <div class="p-3 rounded bg-light-blue"> <strong>Summary:</strong> This paper investigates the effect of intergranular addition of heavy rare earth Dy/Tb-containing alloys on the microstructure and properties of Nd-Fe-B sintered magnets.
