Abstract
The results of numerical simulation of equilibrium magnetization patterns and magnetization reversal in flat cylindrical and elliptical particles of the soft magnetic type are discussed. It is found that the bending state originates in these particles due to instability of quasi-uniform magnetization at large enough in-plane sizes. Similar states exist also in certain intervals of an external magnetic field. It is shown that the magnetization reversal in an elliptical particle depends considerably on the particle thickness and aspect ratio. The nucleation field of an elliptical particle saturates as a function of particle aspect ratio. The effect of a mutual magnetostatic interaction on the magnetic properties of an array of soft magnetic particles is discussed briefly. © 2002 Elsevier Science B.V. All rights reserved.
