The phase stability and magnetic properties of the half-metal-type Co 2Cr 1-xFe xAl alloy system were investigated. It was found that the occurrence of two-phase separation is unavoidable in a concentration range of less than x=0.4, leading to deviation of the saturation magnetic moments from the generalized Slater-Pauling line. The L2 1-type phase becomes stable in a concentration range of more than x=0.7, where no half-metallic behaviors are present. Consequently, it is concluded that the most favorable concentration for applications to spintronic devices is located around x=0.4 in Co 2Cr 1-xFe xAl alloys having the B2-type phase.
