A STUDY OF THE EFFECT OF ANNEALING ON THE HYPERFINE FIELD DISTRIBUTIONS IN Fe_79B_16Si_5 METALLIC GLASS

摘要

A study of the effect of annealing temperatures and time periods on the hyperfine field distributions of Fe_79B_16Si_5 metallic glass near and below the crystallization temperature was carried out using 57~Fe M0ssbauer spectros- copy. The effect of crystallization during annealing as a function of annealing time on the average hyperfine magnetic field, , and the relative change of the probability of hyperfine fields, P(H), with respect to that of the as-received sample are also discussed.
