Mathematical model for the MgB2 hysteresis using parameterized Preisach model

this paper presents a hysteresis model for the mgb2 using a parameterized Preisach model, in which the weighting functions is determined only based on the M-H limiting loop. The results of simulation and experiment of accuracy of the parameterized Preisach model are reported for the case of iron-sheathed MgB2 superconducting cable samples with an external magnetic field perpendicular to its surface.
