Single-Domain Magnetization Curves for the General Ellipsoid

Abstract

Single-domain magnetization curves have been extended to the general ellipsoid. The calculation was carried out on an IBM 705 computer and was an iterative minimization of the energy as a function of the direction of magnetization for an arbitrary applied field. The results are similar to those of Stoner and Wohlfarth for ellipsoids of revolution. Tables containing reduced magnetization as a function of the magnitude and direction of the applied field and shape are available.
