Antiferromagnetic Susceptibility of Chromium Alloys with Non-Transition Metal Elements

Abstract

Antiferromagnetic susceptibilities of Cr_1−xM_x (M=Al, Be, Ge) are calculated in the framework of KKR–CPA. It is shown that the antiferromagnetic susceptibility is strongly enhanced with increasing x, whereas the so-called nesting anomaly is effectively suppressed by the alloying. These results are quite consistent with a magnetic phase diagram seen in the CrAl system.
