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 mdistribution 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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
