Abstract

The magnetic microstructure of rolled-up magnetic nanomembranes is revealed both theoretically and experimentally. Two types of nanomembranes are considered, one with a non-magnetic spacer layer and the other without. Experimentally, by using different materials and tuning the dimensions of the rolled-up nanomembranes, domain patterns consisting of spiral-like and azimuthally magnetized domains are observed, which are in qualitative agreement with the theoretical predictions.

摘要

本文从理论和实验两方面揭示了卷绕磁纳米膜的磁微结构。考虑了两种类型的纳米膜，一种带有非磁性间隔层，另一种则没有。实验上，通过使用不同的材料并调整卷绕纳米膜的尺寸，观察到了由螺旋形和沿方位角磁化的畴组成的畴图案，这与理论预测定性相符。
