| Abstract: | The doping effects of 3d transition metals on the magnetic properties of Os1 − xCrxAl2 are studied by first-principles calculations. The Os1 − xCrxAl2 alloys have high spin-polarizations at the Fermi level with the Cr concentration in the range of 0.0<x?0.625. At higher Cr concentration, the ferromagnetic phase transforms into a ferrimagnetic metallic phase. |
