Ultrafast all optical magnetic switching in plasmonic nanostructures based on the inverse Faraday effect recently has been proposed as a possible route towards magnetic data storage media with very fast writing speed. We have been examined inverse Faraday effect in three different kind of plasmonic nanostructures with Fourier modal method. Our modeling results predict significant enhancement of inverse Faraday effect around all major types of plasmonic nanostructures for a circularly polarized incident light due to surface plasmon polariton propagation near the interface of the metal–dielectric and nonzero value of inverse Faraday effect in this structures even with a linearly polarized excitation unlike the inverse Faraday effect in uniform bulk materials. Also the results show that the field distribution can be varied by changing light wavelength and angle of incidence which opens a possibility to locally control field distribution. Consequently, to affect locally the medium induced magnetization via the inverse Faraday effect and for practical applications in data storage and data processing and also sensing applications can be used widely.
