摘要：

The magnetic and structural properties of Mn1-xCrxAlGe (0 <= x <= 1.0) compounds were investigated. The spontaneous magnetization M-s and Curie temperature T-C of Mn1-xCrxAlGe has a cusp at x = 0.2. The maximum values of M-s and T-C are 1.74 mu(B)/f.u. and 601 K, respectively. It was found that the tetragonal Cu2Sb-type structure was stable for 0 <= x <= 0.75, whereas orthorhombic TiSi2-type structure was observed for x >= 0.8. The reciprocal susceptibility as a function of temperature suggested that the magnetic moment of Cr is antiferromagnetically coupled with that of Mn in Cu2Sb-type structure. (C) 2018 Elsevier B.V.
