Annealing effects on the Curie temperature of a Fe77Cr2B16Si5 glass

Changes in the Curie temperature of a Cr-containing FeBSi glass were studied using DSC measurements. The Curie temperature increases monotonically with annealing temperature and time and the equilibrium value is inversely proportional to the annealing temperature. A uniformly linear log (time) kinetics, as in other Fe glasses containing two metalloids, is found. Results can be explained in terms of the activation energy spectrum model.
