Abstract

Results of research into magnetoelastic change of residual magnetization of cobalt steel annealed at 200—800°C are provided. The value of irreversible magnetoelastic demagnetization is shown to decrease with annealing temperature and become nearly zero after annealing at 600–800°C. In this case, a quasi-reversible (with nearly no hysteresis) change of magnetization is observed. It is explained by the processes of rotation of magnetization vectors when a load is applied.
