High-frequency resistivity of soft magnetic granular films

Co-Zr-O granular films were prepared by reactive sputtering. The films show strong uniaxial in-plane anisotropy as well as good soft magnetic properties and high dc resistivity. In order to confirm their electrical characteristics at high frequency, the frequency and current density dependences of resistivity were investigated. Resistivity was found to be constant over the range measured (up to 18 MHz and 100 MA/m/sup 2/). Furthermore, the films exhibit virtually no hysteresis along the hard… CONTINUE READING
