## Description

- description: The coexistence of superconductivity and magnetism within a single
    material system represents a long-standing goal in condensed matter physics. Van
    der Waals-based moiré superlattices provide an exceptional platform for exploring
    competing and coexisting broken symmetry states. Alternating twisted trilayer
    graphene (TTG) exhibits robust superconductivity at the magic angle of 1.57° and
    1.3°, with suppression at intermediate twist angles. In this study, we investigate
    the intermediate regime and uncover evidence of orbital magnetism. As previously
    reported, superconductivity is suppressed near the charge neutrality point (CNP)
    and emerges at larger moiré fillings. Conversely, we find orbital magnetism most
    substantial near the CNP, diminishing as superconductivity develops. This complementary
    behavior is similarly observed in the displacement field phase space, highlighting
    a competitive interplay between the two phases. Utilizing gate-defined Josephson
    junctions, we probe orbital magnetism by electrostatically tuning the weak links
    into the magnetic phase, revealing an asymmetric Fraunhofer interference pattern.
    The estimated orbital ferromagnetic ordering temperature is approximately half
    the superconducting critical temperature, coinciding with the onset of Fraunhofer
    asymmetry. Our findings suggest that the observed orbital magnetism is driven
    by valley polarization and is distinct from the anomalous Hall effect reported
    at integer fillings in twisted graphene systems. These results offer insights
    into the interplay between superconductivity and magnetism in moiré superlattices.
