THE PSEUDO-PARTICLE HYSTERESIS LOOP IN MIXED-TYPE MODELS OF FINE FERROMAGNETIC PARTICLE SYSTEMS

摘要

In the mixed models, to each small zone of the Preisach plane one associates a pseudo-particle with a hysteresis loop calculated as the average hysteresis loop of he particles from the system with the same switching fields. The shape of the hysteresis loop of each pseudo-particle depends not only on the micromagnetic model of the real ferromagnetic particle but also on the distributions. The analysis of the pseudo-particle hysteresis loop is discussed.
