## Description

- description: Transition metal dichalcogenide moiré homobilayers have emerged as
    a platform in which magnetism, strong correlations and topology are intertwined.
    In a large magnetic field, the energetic alignment of states with different spin
    in these systems is dictated by both strong Zeeman splitting and the structure
    of the Hofstadter’s butterfly spectrum, yet the latter has been difficult to probe
    experimentally. Here we observe a cascade of magnetic phase transitions in a twisted
    WSe2 homobilayer using local thermodynamic measurements. We interpret these transitions
    as the filling of individual Hofstadter subbands, enabling us to extract the structure
    and connectivity of the Hofstadter spectrum for a single spin. The onset of magnetic
    transitions is independent of twist angle, indicating that the exchange interactions
    of the component layers are only weakly modified by the moiré potential. By contrast,
    the magnetic transitions are associated with changes in the insulating states
    at commensurate filling. Our work achieves a spin-resolved measurement of Hofstadter’s
    butterfly despite overlapping states and disentangles the role of material properties
    and moiré superlattices in stabilizing the correlated ground states.
