Abstract :
In this paper, we present a method of using the experimental first-order reversal curves (FORC) distribution as input for Preisach-type models. In order to be able to calculate in the model the integral over the FORC distribution we designed an interpolation algorithm of the three-dimensional (3-D) distribution. The algorithm is validated for a simple case-the output of a classical Preisach model-and then is used for realistic, asymmetrical FORC distributions. Several Preisach-type models are tested for the same FORC distribution and it is shown that the PM2 model gives the best results in simulating magnetization curves starting from the FORC diagram
