Quantum spin size determines whether the Kondo effect suppresses or preserves magnetism

Caption

The size of the spin crucially affects how the system behaves. At spin-1/2, fully quantum spins pair up and cancel each other, so no magnetism appears. At spin > 1/2, larger spins can’t fully cancel, leaving leftover spins that can interact and create magnetic order.
