Abstract We report an experimental study on the effect of
Ag nanoparticles on the polar magneto-optical Kerr effect
in cobalt thin film. The magneto-optical cobalt thin film was
prepared by electron beam deposition method onto the Ag
nanoparticles which were synthesized by laser ablation in
liquid technique. Our results indicate that we have suffi-
cient enhancement of polar magneto-optical Kerr effect of
cobalt thin film around the surface plasmon resonance of
Ag nanoparticles. Moreover, combination of surface plas-
mon resonance of the Ag nanoparticles and very thin Au
layer can be attained the enhancement factor in all of visible
spectral region.
