This page shows my version of a frequency dependent hysteresis model showing a typical behavior like it can be observed with special magnetic materials. Unlike the current pSPICE model, it has full frequency dependency and even contains Barkhausen's effect.

static low frequency behavior with moderate saturation

Coarseness of the Barkhausen steps, the steepness of the saturation area and saturation knee are fully parametric and can be adjusted perfectly accompanying the 4 main field parameters coercivity value, the saturation magnetization and the remaining magnetization. Frequency dependency is fixed included in the model and shows a natural behaviour over a wide frequenc range without parameter changes. However it can be adjusted according to measurements though.

dynamic frequency behavior with stronger saturation  

Typical elliptic behavior of the B-H-curve when it comes to higher  frequencies because of delayed reaction of the Weiss areas and the magnetic domain wall pinning.
