In this study, the magnetic behavior of NiFe/NiO bilayers has been investigated. The relationship between the magnetic properties and interfacial interaction has been briefly discussed. Since magnetic properties of the bilayers are mainly determined by interfacial magnetic interaction, in this article, not only unidirectional interfacial anisotropy has been used to explain exchange field, Hex; also, for the first time, uniaxial interfacial anisotropy is introduced to describe interfacial interaction affecting the magnetic properties, especially coercivity Hc of the bilayers. In addition, a model is proposed to explain the magnetic behavior of the bilayers. The model has been tested by experiment. The experimental results are consistent with the model prediction, and this also confirms the assumption that the magnetization of the bilayer reverses by magnetic rotation.
