摘要/Abstract

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4 g/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50 kHz~2 MHz内变化时样品的巨磁阻抗值，结果显示驱动电流频率f=100 kHz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.
