Annealing kinetics for Curie temperature changes in the amorphous alloy Fe32Ni36Cr14P12B6

Changes in the Curie temperture, T

It was found that T
c
approaches equilibrium values after prolonged annealing, and the kinetics can be described by the distributed activation energies. The activation energy spectrum, however, depends upon the prior quenching condition in a manner similar to that observed for the reorientation of the induced anisotropy and internal friction.
