Influence of Cobalt and magnetic field on the real part of complex permeability–frequency spectra of Finemet nanocrystalline alloys

In this paper the real part of complex permeability-frequency spectra of, , and nanocrystalline alloys were measured for studying the Co influence on the stability of permeability at high frequency regimes for improving frequency application of Finemet alloys. Also these alloys were studying under various AC magnetic fields. It was found that variation of AC magnetic field has little effect on real part of complex permeability spectra of nanocrystalline alloy but obvious changes have been found in real part of μ of , with the change of applied AC magnetic field. This is attributed to the increased pinning field after substitution of Fe with Co in nanaocrystalline alloy.
