|Portuguese Abstract:||We have performed a theoretical investigation of thermal hysteresis in the magnetization of Fem/Dyn /Fem and Gdm/Dyn /Gdm trilayers, where the interface coupling is antiferromagnetic and ferromagnetic, respectively. Our results show a large number of stable states can exist in these structures. The thermal hysteresis occurs because the transitions between these states occur at different temperatures for the heating and cooling pro- cesses. The thermal hysteresis can be quite large, spanning about 90 K. Furthermore the temperature span of the thermal hysteresis can be substantially reduced by applying a modest external magnetic field.|
