Deskripsi
In many quantum magnets, an applied magnetic field competes with the expected zero-field state, leading to complex magnetic behavior. Okuma et al. observe the formation of quantum magnetization plateaus in a kagomé antiferromagnet and argue they form due to the crystallization of magnon excitations.
