The magnetic order in Cr75(Fe0.67Mn0.33)25 alloy prepared under different annealing conditions is studied by means of 57Fe Mssbauer spectroscopy and bulk magnetization measurements.We get the conclusion that the short-range chemical order plays a dominant role in the magnetic order of the alloy.The heat treatment process affects the Cr(Mn)-rich,Fe-rich clusters in the alloy,thus increases both the ferromagnetic and antiferromagnetic transition temperature greatly.The Cr(Mn),Fe clusters lead to the magnetic phase segregation in the alloy.
