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 I_rms=6 mA and frequency from 0.05 kHz to 600kHz. The minimum value of longitudinal magnetoimpedance ratio is down to -52%.
