  • Abstract
    The temperature dependence of the hysteresis loop and the anisotropy field HA of sintered magnets of the composition Nd(Fe0.92-xB0.08Gax)5.5 was investigated using pulsed-field equipment. Analysis based on the nucleation model was performed. The spin reorientation temperatures were determined by measurements of the temperature dependence of the initial AC susceptibility χac(T). It is shown that χac (T) curves can be used to determine the temperature where the FOMP (first-order magnetization process) transition starts
