Abstract

The amorphous Fe40Ni40P x B20−x (x=0, 10, 12, 14, 17) alloys before and after annealing have been studied by means of Mössbauer spectroscopy, etc. Heat treatment of various samples were performed at 225, 250, 275, 300, 325 and 350°C, respectively, for 1 h in a quartz tube in an argon atmosphere. The results show that the magnetic anisotropy and structural relaxation in amorphous Fe40Ni40P x B20−x are related to the phosphorus element concentrations involved and the annealing temperatures. A possible mechanism of two-stage relaxation processes below the glass transition temperature is discussed.
