摘要：

The coercive field of a magnetically soft prismatic grain of irregular cross-section embedded in a hard magnetic matrix has been calculated as a function of the size of the soft magnetic grain. To solve the corresponding two-dimensional micromagnetic problem a finite element technique was used. In spite of large deviation of the spontaneous magnetic polarization in the soft magnetic phase at low external fields, the numerical calculations reveal remarkable high values of the coercive field, if the size of the soft magnetic grains is sufficiently small.
