Anomalous and anisotropic nonlinear susceptibility in the proximate Kitaev magnet α-RuCl3

Abstract The leading order nonlinear (NL) susceptibility, χ 3, in a paramagnet is negative and diverges as T → 0. This divergence is destroyed when spins correlate and the NL response provides unique insights into magnetic order. Dimensionality, exchange interaction, and preponderance of quantum eff...
