Annealing Effects in Ferromagnetic Amorphous Alloys.
Abstract
The kinetics, and therefore probably the atomic mechanism, of the annealing of field-induced anisotropy, Curie temperature, and internal friction have been shown to be the same in certain ferromagnetic amorphous alloys. Disaccomodation can be almost eliminated, and permeability increased, by annealing a zero-magnetostriction amorphous alloy in a perpendicular field. Flash annealing of amorphous alloys permits new annealing treatments that are not otherwise possible. A model of magnetostriction in amorphous alloys relates to the magnitude and sign of the magnetostriction directly to the magnitude and sign of the screening in a screened point-charge model. In particular, the linear magnetostriction is zero if there is no screening. (Author)
