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/软磁双层膜体系的旋转特性;研究结果表明:体系的磁结构表现出了非常丰富的形式,不同的反转机制相应于不同的磁结构。且硬磁层的不可逆反转场较之硬磁层单独存在时要小的多。
Based on the micromagnetic theory, this paper studies the rotational property of the exchange-coupled hard / soft magnetic bilayer by using three-dimension dynamic model. The results show that the magnetization configuration of the exchange-coupled bilayer has various forms, and the different reversal mechanism corresponds to the different magnetic structure. The field of the irreversible hard magnetic layer is much smaller than that of independent hard magnetic layer.
