摘要
实验对在固定直流偏场下产生的硬磁泡(OHB)畴壁中垂直布洛赫线(VBL)的分布均匀性进行了研究.实验发现,泡径越大的硬泡,缩灭场就越大,VBL数目就越多;泡径越小的硬泡,缩灭场就越小,VBL数目就越少,即硬磁泡畴壁中垂直布洛赫线(VBL)是均匀分布的,且存在一个平衡间距.实验结果验证了均匀旋转模型的正确性.
The distribution of vertical Bloch line(VBL) in the domain wall of hard magnetic bubbles generated under a fixed DC bias field was studied by the experiments.The experimental results verify that the radius of hard bubble is larger,the collapse field is higher,the number of VBL is more.On the contrary,the radius of hard bubble is small,the collapse field is lower,the number of VBL is less.The VBL in domain wall of the hard magnetic bubble is uniformly distributed,and there is a balance space.The results confirm that the uniform rotation model is correct.
