摘要： 采用电沉积法制备了厚度为1.1μm到6.9μm的坡莫合金薄膜.经X-射线衍射分析，其结构为fcc 结构，其中NiFe(111)衍射峰的强度明显增强.该薄膜的磁滞回线测量结果表明：其矫顽力随着薄膜厚度的增加而减小.在交流Irms=6mA,频率范围在0.05kHz 到 600kHz 的条件下，纵向磁阻抗比随着薄膜厚度的增加而增加，其最小值可达-52%.

Abstract: The structure of electrodeposited permalloy films with thickness from 1.1μm to 6.9μm is determined to be fcc structure by using X-ray diffraction, which the intensity of NiFe(111) peak increases significantly. Magnetic hysteresis loops of the films demonstrate the decrease of their coercivity values with the increase of the film thickness. Longitudinal magnetoimpedance ratio is measured with an alternating current of Irms=6 mA and frequency from 0.05 kHz to 600kHz. The minimum value of longitudinal magnetoimpedance ratio is down to -52%.
