摘要：
A computer simulation study of magnetization process in bicrystal thin films is presented. Nearly unity squareness is obtained in these films with field applied along the diagonal directions in between the two crystalline easy axes which indicates that the diagonal directions are the effective easy axes. When the field is applied at angles between the effective easy and hard axes, it is found that a magnetization reversal always initiates by forming a transverse domain with magnetization virtually perpendicular to that at the saturation remanent state. The reversal proceeds by forming completely reversed domains within the transverse domains and expanding through the entire film.
