The Thermomagnetic Behaviour of Cobalt Ferrite

Abstract

The small heat changes accompanying the magnetization of cobalt ferrite were measured with two rod specimens. One had been heat-treated to destroy uniaxial anisotropy, the other was untreated. A new method of analysis of the results is described, and while its application to these specimens may not have led to conclusive results, it appears to give useful information when applied to materials of less complex magnetic behaviour.
