研究了非晶态薄带中由各向异性引起的磁化壁稳定化。从磁区观察发现，在退火过程中存在磁区的区域倾向于成为反向磁区的核心和磁区的钉扎点。Fe-Co基合金的壁矫顽力随Fe浓度的增加呈抛物线关系。在高温退火过程中，磁畴壁内部产生的各向异性可能是产生高矫直力的原因之一。研究还表明，具有磁化各向异性的带材作为Wiegand型脉冲产生器具有潜在的应用前景。
The domain wall stabilization caused by anisotropy induced during annealing has been studied in amorphous ribbons. It was found from domain observation that the regions where there existed domain walls during annealing tend to become nuclei of reverse domains as well as pinning sites of domain walls. The increased wall coercive force in Fe-Co based alloys shows parabolic dependence as a function of Fe-concentration. The anisotropy induced within the domain walls during high temperature annealing is expected to be a source of high coercive force. It is also shown that the ribbon with the domain wall induced anisotropy has potential application as a Wiegand type pulse generator.
