| dc.description.abstract | Despite the widespread use of spintronic materials in technology today, their thermal, magnetic
, electronic , elastic instability limits their use in some sectors, especially space applications and the
hydrocarbon sector. In this work, serval properties of full-heusler and half-heusler, and quaternary
alloys were studied by using DFT approximations. Our studies focused specifically on electrical and
magnetic properties in order to develop magnetic materials with high thermal stability for use in
future spintronic applications. Accordingly, several materials have been proposed as new materials
for spintronic applications, such as the full-Heusler alloys (Co2CrAl, and Mn2CrAl) and (CoMnCrAl
, MnCoCrAl) , the half-Heusler ( CoFeGe, CrFeGe, and NiFeGe) in addition to the new half-metallic
series CoRhZrZ (Z = Pb, B, Ga, In, Al, Sn, Si) and ( CoRuCrAl ,CoRhCrAl). The latter shows high
thermal stability of its half-metallic, magnetic, and electronic properties at harsh temperatures. Which
makes it a suitable choice for spintronic applications such as magnetic sensing applications in space
or applications related to the petroleum industries.. | en_US |
