FIELD-DEPENDENCE OF THE REMANENT MAGNETIZATION FOR THIN-FILMS CONTAINING FERRIMAGNETIC PARTICLES

The identification problem for a moving-type Preisach model is solved using the isothermal and anhysteretic remanent magnetization processes. The model's parameters used in the analytical function that describes the reversible magnetization part are determined from the descending major loop branch. The result of the identification algorithm is tested on the dc demagnetization remanence curve and on the Henkel diagram. The agreement between the simulations and experimental data is good; the discrepancies are discussed.
