GMI Effect of FeCoSiB Amorphous Ribbon

Article Preview

Abstract:

The effects of AC frequency, magnetic field strength, ribbon length and test temperature on the Fe72Co8Si15B5 amorphous ribbon’s magnetic impedance were studied. The results showed that the resistance, reactance and impedance of amorphous ribbons increased with the increase of AC frequency, but decreased as magnetic field strength decreased; the rangeability of resistance, reactance and impedance increased as AC frequency and magnetic field strength increased; the resistance and reactance increased as ribbon length increased; the ribbon had a good temperature stability in resistance.
