摘要：

The electronic structures were systematically calculated for Hensler alloys X(2)YZ (X and Y = 3d transition element, Z = IIIb, IVb, Vb element). The results show that alloys FC(2)CrZ have the high density-of-state at the Fermi energy in the majority-spin state and show high spin polarization. The effects of chemical disorder on the half-metallicity and magnetic moment are discussed on the basis of the electronic structures. Considering three types of chemical disorder, we show that among the alloys Fe(2)CrZ, there are high spin polarized materials insensitive to chemical disorder and that Fe-Cr chemical disorder may occur.
