## Description

- description: Graphene and transition metal dichalcogenide flat-band systems show
    similar phase diagrams, replete with magnetic and superconducting phases. An abiding
    question has been whether magnetic ordering competes with superconductivity or
    facilitates pairing. For example, recent studies of Bernal bilayer graphene in
    the presence of enhanced spin–orbit coupling show a substantial increase in the
    observed domain and critical temperature Tc of superconducting states; however,
    the mechanism for this enhancement remains unknown. Here we show that introducing
    spin–orbit coupling in rhombohedral trilayer graphene (RTG) by substrate proximity
    effect generates new superconducting pockets for both electron and hole doping,
    with maximal Tc ≈ 300 mK, which is three times larger than in RTG encapsulated
    by hexagonal boron nitride. Using local magnetometry, we show that superconductivity
    straddles a transition between a spin-canted state with a finite in-plane magnetic
    moment and a state with complete spin–valley locking. This transition is reproduced
    in our Hartree–Fock calculations, in which this transition is driven by the competition
    between spin–orbit coupling and the carrier-density-tuned Hund’s interaction.
    Our experiment suggests that the enhancement of superconductivity by spin–orbit
    coupling is driven by a quantitative change in the canting angle rather than a
    change in the ground state symmetry. These results align with a recently proposed
    mechanism for the enhancement of superconductivity15, in which fluctuations in
    the spin-canting order contribute to the pairing interaction.
