Antiferromagnetism in disordered B.C.C. Cr-Mn Alloys

Abstract

The neutron diffraction, electrical resistivity and magnetic susceptibility measurements on b.c.c. Cr-Mn alloys containing manganese from 7.0 to 25.3 atomic percent have shown that the alloys are antiferromagnetic but disordered atomically. The obtained results are shown to be compatible with the theoretical conclusions from the spin density wave model.
