The microscopic magnetic textures of isospin symmetry-broken phases in rhombohedral tetralayer graphene have been directly imaged. By probing spin orientation and magnetic anisotropy at ultra-low fields, key energy scales — the spin–orbit coupling and intervalley Hund’s exchange — have been extracted, shedding new light on the phase hierarchy in strongly correlated electron systems.
