摘要：
With the aim of improving and investigating magnetocaloric insights for spintronic applications, we investigated the electronic structure of Cr-doped AlSb compounds via first-principles calculations using the KKRCPA-DFT method. Here, we investigated the stability of alloy materials as a function of magnetic contamination. A stable semimetallic ferromagnetic phase can be obtained by introducing the Cr element into AlSb, which is inherent in nonmagnetic semiconductors. The total magnetic moment of the doped material changes from 0.1167 mu B to 0.716 mu B for 4% and 25% Cr, respectively. Curie temperature changed to 740 K at 25% Cr concentration.
