沉积态(Fe88Zr7B5)0.97Cu0.03软磁合金薄膜的磁性和巨磁阻抗效应
, PP. 1295-1298
Keywords: Fe-Zr-B-Cu非晶薄膜,软磁性能
Abstract:
采用射频溅射法在单晶硅衬底上制备了(Fe88Zr7B5)0.97Cu0.03非晶软磁合金薄膜样品,对沉积态样品的软磁性能和巨磁阻抗(GMI)效应进行了实验研究与机理分析．结果表明,未掺Cu元素的Fe88Zr7B5沉积态合金薄膜几乎无GMI效应,而掺了适量Cu元素的(Fe88Zr7B5)0.97Cu0.03合金薄膜在沉积态下即具有显著的GMI效应．在13MHz频率下,最大纵向磁阻抗比达17%,最大横向磁阻抗比为11%,这表明(Fe88Zr7B5)0.97Cu0.03非晶合金薄膜在沉积态已具备优异的软磁性能和巨磁阻抗效应．同时讨论了该薄膜样品的巨磁阻抗效应随频率的变化特性.
