Abstract
Hansen, and Koch, Steeg and de Vos reported the reversible change of coercive force during the process of over-aging and re-aging treatments of an Alnico-5 magnet alloy. In the preceding paper, the authors have shown that the interphase boundary migrates reversibly during the process. Further researches have been made by measuring the coercive force and the saturation magnetization as functions of temperature and time. It has been concluded that the reversible change in coercive force is associated with the reversible interphase boundary migration and the reversible shift of the lower curie point of the weakly magnetic phase.
