Abstracts

EN

It was shown that magnetic reluctivity measured versus time after demagnetization for pre-annealed samples of the Fe_{72}Co_{10}Nb_6B_{12} amorphous alloy exhibits highly non-exponential behavior which can be described by the coupling model. The relaxation intensity and the coupling parameter describing correlation effects in free volume diffusion decrease with increasing 1 h annealing temperature indicating annealing out of free volume and formation of iron clusters in amorphous matrix.
