Nonlinear magneto-optical (MO) effects generally refer to standard nonlinear optical phenomena that emerge upon magnetization of a material. The nonlinearity of MO effects themselves, however, has been largely unexplored despite its promise as a novel pathway to develop functional MO devices. In this study, we observe the nonlinearity of MO Kerr effect(MOKE) in indium tin oxide (ITO) with epsilon–near–zero (ENZ) property in the near infrared.
