Abstract

This paper addresses the problem of asymmetry of the First-order Reversal Curve (FORC) diagram in correlation with the symmetry of the Preisach distribution. Only in a few cases, for the exchange-bias materials for example, an asymmetric distribution in the demagnetized state has to be considered in the Preisach model. In relation to the case of exchange bias materials a correlation between the distribution of interactions and that of the coercivities was considered. The FORCs starting on the ascending and descendent branches of the major loop are calculated with a Moving Preisach Model. The results show a good resemblance with typical experimental results on exchange bias materials.
