| 摘 要： | 采用单脉冲电沉积技术制备NiFe/Cu复合材料,对制备材料的巨磁阻抗进行了研究。结果表明,镀液中硫酸亚铁体积质量为4g/L时,材料的巨磁阻抗具有最大值。研究了材料巨磁阻抗与驱动电流频率f的关系,测量了驱动电流频率在50kHz～2MHz内变化时样品的巨磁阻抗值,结果显示驱动电流频率f=100kHz时,样品的GMI效应最大,其值为190%。

| Abstract: | Giant Magnetic Impedance（GMI） of NiFe/Cu Composite Material disposed by single pulse electrod eposition technology was studied.The results show that the GMI reach maximum when the ferrous sulfate content in plating solution was 4 g/L.On the other hand,the GMI value of sample was measured which change with the drive current frequency f from 50 kHz to 2 MHz in order to discuss the relationship between GMI and drive current frequency,the results show that the GMI of sample reach maximum value 190% when the f equal to 100 kHz. |
