Popis: The temperature variation of the residual magnetization of the precipitation-hardened alloys Alnico and Ticonal is considered. The temperature hysteresis of the magnetization due to the irreversible magnetization reversal of single-domain particles is related to the temperature dependence of the anisotropy constant and the value of the demagnetizing field. The magnetic state of the matrix phase affects the irreversible process of magnetization reversal of the strongly magnetic particles. The residual magnetization may include a component due to superparamagnetic inclusions in the matrix phase, giving a contribution to the temperature hysteresis in heating-cooling cycles.
