Abstract
Five crystals of nominal composition Co0.1Fe2.9O4, grown from the melt under different partial pressures of oxygen, were subjected to magnetic annealing at 100°C. The relaxation time characterizing the annealing process is shown to increase from several minutes for crystals known to contain cation vacancies to a value too large to be determined for a crystal essentially stoichiometric with respect to oxygen content. The observed changes in relaxation time and magnitude of the anneal‐induced anisotropy are interpreted as the effect of cation vacancies on the ease of movement of cobalt ions between equivalent cation sites during the annealing process.This publication has 6 references indexed in Scilit:
