Abstract—The scaling law of minor loops was studied on an soft magnetic nanocrystalline alloy Fe72.5Cu1Nb2Mo1.5Si14B9. An analytical expression for the coercive force in the Rayleigh region was derived. The coercive force is connected with the maximal magnetic field Hmax via the reversibility coefficient μi/ηHmax. Reversibility coefficient shows the relationship between reversible and irreversible magnetization processes. A universal dependence of magnetic losses for hysteresis Wh on the remanence Br with a power factor of 1.35 is confirmed for a wide range of magnetic fields strengths.

Index Terms—soft magnetic nanocrystalline alloy, minor hysteresis loop, Rayleigh law, remanence, coercive force.
