  • Abstract
    The anisotropy field as well as the coercivity of technical, sintered permanent magnets based on Nd-Fe-B was measured from 80K up to the Curie temperature using a pulsed field system. It was tried to correlate the temperature dependence of the coercivity with that of the anisotropy. A general correlation of the type:IHcprop. (HA)kwas found, where the power "k" lies between 1.5 and 3. The power "k" decreases with decreasing temperature showing either a temperature induced change of the coercivity mechanism or the influence of K2.
