On the Nature of Spontaneous Rectangular and Square Hysteresis Loops in Ferrites

Inorganic Materials Aims and scope

Abstract

The conditions necessary for producing rectangular- and square-loop ferrites are inferred from analysis of new and earlier reported experimental data. The effect of microinhomogeneities on the properties of such ferrites is investigated. It is shown that α-Fe2O3 inclusions, local tetragonal distortions, and linear microinhomogeneities have an adverse effect on their magnetic properties and that the high values of H t/H c in all rectangular-loop ferrites are due to aggregated microinhomogeneities containing increased concentrations of cation vacancies compared to the host material. The origin of such inhomogeneities is discussed.
