ANNEALING EFFECTS ON CURIE TEMPERATURE IN AMORPHOUS Fe-B-Cr-Si ALLOY

In this paper, annealing effects on the curie temperature （Tc） in amorphous Fe-Cr-B-Si alloy have been investigated by using the curie temperature measurement apparatus specially for straight ribbon samples. Logarithmic dependence of the increment of Tc upon annealing time（t）has been obtained from computer fitting, and two processes in structural relaxation causing changes in Tc have been discussed.
