文摘

In this paper a Preisach-type model, named Preisach model for patterned media (PMPM, or PM²), that successfully describes magnetization processes in structured particulate ferromagnetic media and in strongly correlated particulate media is presented. The PM² provides explicit expressions for the magnetization curves, which makes it numerically very efficient. It obeys the exact wiping-out property and describes non-congruent minor hysteresis loops measured within given field limits.
