AB - A microstructure based magnetization reversal model is presented for sintered Fe-Nd-B magnets. The model makes use of a position dependent domain wall energy profile to correlate the intrinsic coercivity, iH c (and the nucleation field) to the magnetocrystalline anisotropy field. The inferences of the model are verified through the study of the effect of Dy and Ce additions on the iHc as well as by examining the temperature dependence of iHc and anisotropy field existing in published literature. It is inferred from this model that selective modifications of the interfaces could lead to appreciable improvements in the magnetic properties.
