Abstract in brief

The study explores how multilayer graphene (Rhombohedral multilayer graphene) exhibits magnetism that arises from itinerant electrons near a Van Hove singularity, showing features like spontaneous spin and valley polarization, but with signatures of local magnetic moments indicated by entropy measurements.
A key finding is the observation of a Pomeranchuk effect, where the fluctuating magnetic moment phase is entropically favored over the symmetric Fermi liquid at certain temperatures, suggesting a decoupling of spin and valley polarization from electron itinerancy.
Transport measurements reveal a finite-temperature resistance minimum linked to the interaction between fluctuating magnetic moments and electron-phonon scattering, emphasizing the universal behavior of soft isospin modes in two-dimensional flatband systems.]
