## Description

- description: Flat bands and electron correlation in moiré lattices give rise to
    many exotic phases, including Mott insulators, superconductivity, and topological
    states. Within the first moiré band, integer and fractional quantum anomalous
    Hall effects have been observed in twisted bilayer MoTe2 (tMoTe2) at one hole
    doping and fractional doping per moiré unit cell, respectively. When the second
    moiré band is fully hole doped, quantum spin Hall insulator has also been reported
    in tMoTe2 at a certain twist angle. Exotic topological states together with ferromagnetic
    (FM) states in the high moiré band can potentially exist as well. In this study,
    we report the observation of a FM phase in the second moiré band in tMoTe2. The
    FM phase can be tuned by both the doping level and displacement field. At filling
    around 2.58 holes per moiré unit cell, the FM phase reaches a Curie temperature
    of 3.5 K. A large displacement field can sup- press the FM phase, like the FM
    phase at the filling of -1. Our results demonstrate the realization of time-reversal
    symmetry-breaking states in the higher moiré bands in tMoTe2.
