Precision Determination of Anisotropy Constant K1 from Magnetization Curve of Partially Aligned Unaxial Anisotropy System
Journal of Magnetics, Volume 6, Number 4, 31 Dec 2001, Pages 142-144
Abstract
A method to deduce the rotational magnetization curve from experimental magnetization of partially aligned uniaxial anisotropy system has been investigated. The curve obtained by this process has been evaluated quire close to the theoretical magnetization curve compared to that obtained by linear extrapolation from high field data. This new approach offers better accuracy for the determination of magnetic anisotropy by fitting a calculated magnetization curve to the obversed one.
