    Graphene at Room Temperature

## Description

- description: In this Letter, we report the discovery of giant room-temperature odd-parity
    magnetoresistance (OMR) in a bilayer graphene heterostructure interfaced with
    Cr2⁢Ge2⁢Te6 (CGT). We show that the OMR is electrostatic gate-voltage tunable,
    exhibiting maximum value near the graphene band edges and diminishing rapidly
    with increasing charge carrier density. Our theoretical analysis reveals that
    the OMR originates from the coupling of out-of-plane components of Berry curvature
    and orbital magnetic moment with the applied magnetic field, signaling intrinsic
    time-reversal symmetry breaking in the system. This time-reversal symmetry breaking
    persists at room temperature within the CGT and bilayer graphene heterostructure
    despite the bulk CGT exhibiting ferromagnetic transition at 65 K. Our Letter opens
    new avenues for probing band geometric phenomena through magnetotransport measurements,
    especially in quantum materials where the anomalous Hall effects are immeasurably
    small due to the extrinsic scattering-dependent contributions canceling Berry
    curvature contributions.
