Lodder}, title = {Observation of strong magnetic effects in visible-infrared sum frequency generation from magnetic structures}, abstract = {We have observed very strong magnetization-induced changes of the infrared-visible sum-frequency generation (SFG) intensity from thin magnetic films using 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 surface plasmon-polaritons. The magnetization dependence of this resonance opens the way for nonlinear magneto-optical SFG studies of magnetic surface excitations.}, year = {2000}, journal = {Physical Review B}, volume = {62}, number = {2}, pages = {R783-R786}, month = {Jul 1}, isbn = {1098-0121; 1550-235X}, doi = {10.1103/PhysRevB.62.R783}, language = {eng}, }
