Tailoring Magnetic Exchange Interactions in Ferromagnet-Intercalated MnBi2Te4 Superlattices
Abstract The intrinsic magnetic topological insulator MnBi 2 Te 4 (MBT) has provided a platform for the successful realization of exotic quantum phenomena. To broaden the horizons of MBT-based material systems, we intercalate ferromagnetic MnTe layers to construct the [(MBT)(MnTe) m ] N superlattices by molecular beam epitaxy. The effective …
