摘　　要：以Fe Cu Nb Si B软磁粉为复合相,丁基橡胶为基体制得复合薄膜;采用Gwimstek-8001G-LCR数字电桥测试,在4k Hz、10k Hz、100k Hz、1MHz的不同频率下,观察薄膜的阻抗Z随外磁场磁感应强度B的变化情况。研究结果表明复合薄膜在小于0.4Gs弱磁感应强度、低于10k Hz测试频率下磁敏性能最好,可用作新型柔性磁敏感传感器的开发。A thin film was constructed by mixing Fe Cu Nb Si B soft magnetic powder with butyl rubber. Performance of the thin film,the correlations of impedance Z with external magnetic field B,were tested at frequencies of 4k Hz,10 k Hz,100 k Hz and 1MHz with a Gwimstek- 8001G- LCR. The research results displayed that the film had its best magnetic properties under 0. 4Gs magnetic field and below 10 k Hz test frequency. It can be used to develop new flexible magnet sensitive sensors.
