Abstract
Magnetization reversals in high magnetocrystalline anisotropy materials like barium ferrite are believed to take place by coherent rotation or by reverse‐domain nucleation. The former mechanism gives rise to a Stoner‐Wohlfarth type of angular variation of coercive force and the latter mechanism gives rise to Kondorsky‐type behavior. Angular variation of coercive force was measured in several oriented particle assemblies with the average particle size ranging from 0.4 to 200 μ. The results were interpreted by a simple model incorporating SW and Kondorsky behavior.This publication has 4 references indexed in Scilit:
