Interrelation of Hysteresis Characteristics of a Soft Magnetic Nanocrystalline Alloy

Resumo

The relationships which interconnect parameters of static magnetic hysteresis loops, namely, hysteresis losses, coercive force, and remanence, have been obtained. These relationships arise from the similarity of dimensionless hysteresis quantities in the magnetic field range corresponding to the increase in the magnetic permeability. An experimental check was performed using the soft magnetic nanocrystalline Fe_72.5Cu₁Nb₂Mo_1.5Si₁₄B₉ alloy. It was shown that, at given values of magnetic induction B_max and magnetic field H_max, the required hysteresis quantity can be calculated using experimental values of the other hysteretic quantities.
