摘要
基于文献 [17]和 [18]提出的铁磁 非铁磁 铁磁层状薄膜的电磁模型 ,详细研究了层状薄膜的巨磁阻抗增强效应 ,以及磁性层和非磁性层厚度与层状薄膜的巨磁阻抗效应的关系 .分析表明 ,铁磁层和非铁磁层薄膜的电阻率相差越大 ,越有利于获得显著的巨磁阻抗效应 ;对于总厚度要求一定的层状薄膜 。
Based on the electromagnetic model of ferromagnetic/non\|ferromagnetic/ferromagnetic layered films proposed in references \ and \,the enhanced giant magneto\|impedance (GMI) effects and the GMI ratio dependence on the thickness of the constituent thin films are analyzed numerically in detail.It is showsn that larger difference of resistivity between the ferromagnetic and non\|ferromagnetic layers as well as an optimum thickness of the layered thin films are beneficial to the improvement of the GMI effects.
