Abstract

In this article, a modification is suggested for a hysteresis model to become completely adequate for nanocrystalline CoFe2O4 hysteresis. A verification of the modified model was carried out, showing good agreement between simulation and experimental measurements of nanocrystalline CoFe2O4 calcined at different temperatures or pressed at different pressures. A prediction of the hysteresis loss of nanocrystalline CoFe2O4 was formulated and estimated as a result of the modified model.
