摘要
以微磁学理论为基础采用三维动力学模型研究了交换耦合硬/软磁双层膜体系的反磁化机制;研究结果表明:在三维模型下,随着软磁层厚度的改变,体系的反磁化过程表现出了非常丰富的形式;硬磁层主要是通过形核的畴壁移动来实现其反磁化过程的.且硬磁层的磁化反转形式不仅与软磁层的尺寸密切相关而且与硬磁层的厚度也有一定的关系.
This paper is based on the micromagnetic theory to study the magnetization reversal mechanism of exchange-coupled hard /soft magnetic bilayer by using three-dimension dynamic model.The results show: in the three-dimension dynamic modal,with the change of the thickness of soft layer,there is a rich magnetization reversal form.For the hard magnetic layer,the magnetization reversal process belongs to displace of the domain wall of formed nucleus;And we find the magnetization reversal form of the hard layer is not only related with the thickness of soft layer,but also related with the thickness of hard layer.
