Charge-transfer-induced re-entrant ferromagnetism in twisted-bilayer-MoTe2/hBN/WSe2

doi:10.1088/1674-1056/ae1c27

Abstract Ferromagnetism in moiré flat-band systems has been extensively studied in the first valence miniband of twisted MoTe$_2$, while its controlled realization at higher moiré fillings remains largely unexplored, except for very recent works reporting correlated magnetism near half filling of the second moiré band. Here, we investigate rhombohedral-stacked twisted MoTe$_2$/hBN/WSe$_2$ heterostructures and uncover two distinct ferromagnetic (FM) regions: one centered near ${v}_{\rm h} \approx 3$ (half filling of the second moiré valence miniband) at zero displacement field, and a re-entrant FM phase that emerges for ${v}_{\rm h} > 3$ only under a finite out-of-plane electric field. These FM regions are separated by a narrow filling window with a strongly suppressed magnetic circular dichroism (MCD) response. Layer-sensitive exciton spectroscopy identifies that WSe$_2$ is hole-doped in the re-entrant FM region, consistent with partial charge transfer from MoTe$_2$ to WSe$_2$. We propose that electric-field-induced layer repopulation stabilizes the re-entrant ferromagnetic phase by pinning the effective MoTe$_2$ filling near ${v}_{\rm h} \approx 3$ while adding carriers to the remote WSe$_2$ layer. Our results demonstrate that remote-layer population control is an effective tuning knob for magnetic ordering in higher moiré minibands, extending the design space for correlated spin-valley phases in transition metal dichalcogenide heterostructures.
