  text: Bilayer graphene, rotationally faulted to ~1.1 degree misalignment, has recently
    been shown to host superconducting and resistive states associated with the formation
    of a flat electronic band. While numerous theories exist for the origins of both
    states, direct validation of these theories remains an outstanding experimental
    problem. Here, we focus on the resistive states occurring at commensurate filling
    (1/2, 1/4, and 3/4) of the two lowest superlattice bands. We test theoretical
    proposals that these states arise due to broken spin—and/or valley—symmetry by
    performing direct magnetic imaging with nanoscale SQUID-on-tip microscopy. This
    technique provides single-spin resolved magnetometry on sub-100nm length scales.
    I will present imaging data from our 4.2K nSOT microscope on graphite-gated twisted
    bilayers near the flat band condition and discuss the implications for the physics
    of the commensurate resistive states.
