Preisach studies on ZFC/FC magnetization behavior of sintered SrRuO3

Zero-field-cooled (ZFC) magnetization, field-cooled (FC) magnetization, AC magnetic susceptibility and major hysteresis loops of sintered SrRuO3 have been measured over the range of magnetic ordering temperature. The data were analyzed within the framework of the Preisach model. The numerical simulations match the major features of ZFC/FC magnetization. The results indicate that various ZFC/FC behaviors originate from the applied field and the Barkhausen spectrum of the sample
