Study of the Effect of Annealing on the Hyperfine Field Distributions in Fe79B16Si5 Metallic Glass

Study of the effect of annealing temperatures and time periods on the hyperfine field distributions of Fe79B16Si5 metallic glass near and below the crystallization temperatures were made by using 57Fe Mössbauer spectroscopy. The effect of crystallization during annealing as a function of annealing time on the average hyperfine field (〈H〉) and the relative change of the probability of hyperfine fields, P(H), with respect to that of as received sample have also been discussed.
