摘要: The magneto-optical Kerr effect (MOKE) of light scattered from plasmon-resonant Ag particles placed near a magnetic sample is investigated. were deposited on sputtered NiFe films with an SiO2 spacer layer known thickness. MOKE signal in the was found to vary strongly observation angle. For s-polarized incident light, no rotation normal direction, and switched sign as direction passes through surface direction. Conversely, p-polarized generated nonzero In general, increased for decreasing thickness, addition angular distribution changed, both s- p-incident polarizations. Implications near-field optical microscopy using probes are discussed.
