This compound are found to be half -metallic ferromagnets with a total magnetic moment of 2.25渭B per Fe. In addition to this, we reported the DRX measurements of the thick iron sample before and after annealing. One should note, after the annealing treatment at a higher temperature, the disappearance of the peak associated to the Fe(001) plane. In contrast to this report, we observed after the annealing at low temperature the additional peaks attributed to the presence of indium and Fe2As. This suggests a subsequent process consisting in a strong migration of atoms followed with crystallization at the higher temperature.To investigate the origin of magnetism and electronic structure in these zb compounds, we calculated the total and partial DOS of FeInP.One can see that 碌total=4.24碌Band 碌Fe=3.27碌B in contrast 碌In=0.021碌B and 碌P=0.049碌B.These results predicted that FeInP compound do belong to the class of zb half metallic HM ferromagnetswith a pseudo gap= 0.93 eVare more promising materials for spintronics devices. <iframe src="https://publications.waset.org/abstracts/39717.pdf"
