The Effect of Heating on the Magnetic Properties of Fe_71,5Cu₁Nb₅Si_16,5B₆ Amorphous Film

Abstract:

This article describes the results of measuring the temperature dependence of saturation magnetization of amorphous film on an iron basis at different temperatures with preliminary heating of the sample. The temperature curves were obtained for a sample without prior heating and for a sample after annealing at temperatures exceeding the temperature of crystallization. It is shown that the Curie temperature of the sample after annealing increases, the temperature dependence of the magnetization is described by the quantum-mechanical equation of state of crystalline magnetic materials (the Brillouin function). Annealing at 820°C leads to the formation of two magnetic phases with the Curie temperatures of approximately 400 and 650°C. The emergence of the two phases is accompanied by a sharp increase in the residual magnetization and coercive force of the sample.
