Anisotropy Properties of Hexagonal Ferrimagnetic Oxides

Abstract
The effects of the incomplete alignment of all magnetic moments of a sample in an applied field on the torque curves are discussed. Examples are given of torque curves determined for cobalt-substituted hexagonal compounds of the ferroxdure type with low anisotropy. It is shown that the characteristic details of these curves can be interpreted in terms of this incomplete alignment, both on a microscopic and an atomic scale.
