摘要：

A simultaneous breaking of space and time-reversal symmetry leads to a coexistence of crystallographic chi(ijk)((2))(2 omega) and magnetization-induced chi(ijkl)((3))(2 omega) electric-dipole type contributions to the non-linear optical susceptibility in the same medium. As a consequence, a new transversal nonlinear magneto-optical effect arises that is linear in M. This effect is experimentally demonstrated in thin films of magnetic garnets, as well as large effects quadratic in M. We suggest a novel method to distinguish the two susceptibility contributions based on their different transformation properties.
