摘要
We present a mean-field model with competing interlayer interactions which give rise to organized frustration. The frustration arises due to the difference in modulation length of the interlayer exchange coupling in the mixed-spin state. We calculate the energy landscapes and the equations of state of the system and show how multiple configurations are possible. In addition, the study shows how in such a layered system with competing interactions magnetization jumps can occur at low temperature due to the sharp energy barriers in the landscape. Finally, we examine possible mechanisms of magnetization self-reversal via layer-moment switching.
