Interrelation of Hysteresis Characteristics of a Soft Magnetic Nanocrystalline Alloy

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 72.5 Cu 1 Nb 2 Mo 1.5 Si 14 B 9 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.
