Effect of surface hybridization on RKKY coupling in ferromagnet/topological insulator/ferromagnet trilayer system
We theoretically investigate the RKKY exchange coupling between two ferromagnets (FM) separated by a thin topological insulator film (TI). We find an unusual dependence of the RKKY exchange coupling Φex on the TI thickness (tTI). First, when tTI decreases, the coupling amplitude increases at first a...
