Abstract
We have observed very strong magnetization-induced changes of the infrared- visible sum-frequency generation (SFG) intensity from thin magnetic films u sing a free electron laser as a tunable infrared source. With the help of a magnetic grating a clear resonance is observed due to the excitation of su rface plasmon-polaritons. The magnetization dependence of this resonance op ens the way for nonlinear magneto-optical SFG studies of magnetic surface e xcitations.
