讨论了高压洛伦兹电子显微镜观察到的 Fe77Nd15B8 合金烧结永磁体的静态和动态壁。发现晶界三重结附近的 180° 壁(其结构为 bcc 相)被强烈钉扎,而其他壁很容易移动消失。 bcc 相边界区域是铁磁性的,因为壁进入该区域。还讨论了在施加场的影响下 180° 墙壁移动的观察结果。
Static and dynamical walls in sintered permanent magnets of Fe77Nd15B8alloys observed by high voltage Lorentz electron microscopy are discussed. A 180° wall near a triple junction of the grain boundaries whose structure is a bcc phase was found to be strongly pinned, whereas other walls easily moved to disappear. The bcc phase boundary region is ferromagnetic since the wall emergies into this region. The observation of 180° walls moving under the influence of the applied field is also discussed.
