Our experimental measurements for the magnetization M as a function of temperature are analyzed for the multilayer structure of CoMn1-x Fe (x) Ge for x = 0.085 and x = 0.12 at constant magnetic fields of 3, 5, and 7 T. For this analysis, a power-law formula is used below the transition temperature T-C for these compositions and the values of the critical exponent beta for the magnetization M (order parameter) are determined. Our analysis indicates that a first order transition at lower concentrations (x = 0.085) changes toward a second order at higher concentrations (x = 0.12) at constant magnetic fields (3, 5, and 7 T) for the multilayer CoMn1-x Fe (x) Ge, as observed experimentally.
