Abstract
We have characterized the spectroscopic magneto-optical response of a ${({\text{Pr}}_{0.4}{\text{La}}_{0.6})}_{0.7}{\text{Ca}}_{0.3}{\text{MnO}}_{3}$ thin film in the visible. We find, in addition to the conventional linear magneto-optical response, two distinct nonlinear contributions corresponding to the quadratic magneto-optical and the magnetorefractive effect, respectively. These nonlinear effects appear with dissimilar intensity depending on the temperature and the light frequency. Strikingly, these nonconventional responses can be one or two orders of magnitude larger than the linear magneto-optical effect. This phenomenon is related to the complex electronic behavior of this manganite and probably can be expected also in other correlated electronic systems with strong spin-lattice coupling.
