| 摘 要： | 采用磁控溅射法制备了Cu/FeNi复合结构丝,并对其结构及巨磁阻抗(GMI)效应进行了研究.结果表明,Cu/FeNi复合结构丝具有良好的GMI效应,在较低频率下观察到的最大磁阻抗变化可达247.4%,同时发现FeNi铁磁层厚度对复合结构丝的软磁性能有重要影响,找到了复合结构丝铁磁层最佳厚度的范围,当厚度达到一定值时铁磁层内磁矩方向由环向分布转向复合丝长轴方向,表现出不同的GMI行为.

| Abstract: | The Cu/FeNi composite-wires were prepared by RF magneto-sputter equipment in this paper. The investigation of magnetic properties and giant magnetic impendence effect of wires were presented. The results show that Cu/FeNi composite-wires possess better soft magnetic properties. The maximum of MI ratio reaches 247.4% at a low frequency and the FeNi coating thickness has great influence on soft magnetic-properties of the wires. We find the optimum thickness. When the coating thickness is big enough, the magnetic moments direction of the magnetic film are orientated from the initial circumferential direction to the longitudinal direction. Hence,we concluded there are different GMI behaviors in the composite wires. |
