Rotation of Isolated Spherical Ferromagnetic Single Domains Subjected to Varying Magnetic Field and Strain

摘要

This paper develops a limited model representative of ferromagnetic materials employing the ferromagnetic domain as the basic building block. The effects of the magnetostatic field, magnetocrystalline anisotropy, and magnetoelastic stress on domain rotation are considered. The process of domain rotation from an unstable state to a stable one is included in the model. The model is simulated by a computer program, and representative sets of hysteresis loops are obtained. Previous investigations are briefly discussed and contrasted with the present study.
