摘    要:采用磁控溅射法制备了Ni80Fe20/Fe50Mn50/Ni80Fe20/Cu复合结构丝,研究了外层Ni80Fe20厚度、驱动电流大小及频率等变化对非对称巨磁阻抗(AGMI)效应的影响。实验结果表明,随着外层Ni80Fe20厚度增加,铁磁-反铁磁的交换耦合作用呈现逐渐减小的变化规律。固定内层Ni80Fe20、Fe50Mn50、Cu厚度分别为0.85、0.5和30μm,外层Ni80 Fe20厚度为1.72μm,驱动电流为10mA,频率为1MHz左右,AGMI效应最明显。

关 键 词:磁控溅射  AGMI  复合结构丝

Abstract:In this paper,Ni80Fe20/Fe50Mn50/Ni80Fe20/Cu composite wires were prepared by magnetron sputtering.The influence of the outer layer Ni80Fe20 thickness,driving current,frequency on AGMI effect were investigated.The results showed that with the increase of the outer layer Ni80Fe20 thickness,ferromagnetic-antiferromagnetic exchange coupling effect firstly increases then decreases.When thickness of the interlayer Ni80Fe20,Fe50Mn50,Cu were controlled at 0.85,0.5,30μm respectively,the most obvious AGMI could be obtained with the outer-layer Ni80Fe20 of 1.72μm at 1MHz when driving current is 10mA.
Keywords:magnetron sputtering  AGMI  composite wires
