Abstract

In the paper one presents the relation between the Preisach-type models in which the interaction field distribution is state dependent and the FORC diagram. The method used for the calculation of the FORC diagram is extended to Multiple Order Reversal Curves (MORC) that can cover minor hysteresis loops. The relation between the MORC and FORC diagrams is presented and it is shown that FORC-type method can be used with sufficient accuracy when in the experiment the saturation is not reached..
