摘要：

By incorporating random interfacial exchange interaction into the Landau-Lifshitz-Gilbert equation, we show that magnetization reversal of exchange-biased films possesses unique hysteresis features. A detail magnetization reversal process for different ferromagnetic layer thickness is analyzed. (C) 2000 American Institute of Physics. [S0003-6951(00)02129-X].
