Magnetic properties and giant magneto-impedance (GMI) effects of FeCuCrVSiB single layered and multilayered films with Ag as the central layer and SiO2 as the isolating layers, which were prepared by radio frequency sputtering without field and with a magnetic field about 72kA/m along the films length, are investigated. The hysteresis loops of single layered films show that the samples deposited with a magnetic field possess excellent soft magnetic properties and the coercive force is only about 64A/m. After annealing at an optimum temperature of 230℃ for 1.5h, the maximum GMI ratios of single layered films are 37.5% in transverse field at the frequency of 13MHz, and the maximum GMI ratios of multilayered films is 277% at the frequency of 8.6MHz. The frequency dependence of the magneto-impedance indicates that the GMI effect in multilayered films can be very large even at relatively low frequencies.
