摘要：

Materials with high spin polarization at the Fermi energy (E-F.) are searched by the systematic band Calculation For Heusler alloys X(2)YZ. It is shown that materials with high density-of-state (DOS) for the majority-spin state at the E-F tend to maintain high spin polarization against chemical disorder. Such materials are predicted, using the characteristics of DOS of Heusler alloys. As a candidates. X-2(CrxMn1-x)Z will be proposed, where X is combination between transition elements including at least one of Fe, Ru and Os, and Z is combination among IIIb, IVb and Vb elements.
