Plasmon-assisted high reflectivity and strong magneto-optical Kerr effect in permalloy gratings

Kostylev, Nikita; Maksymov, Ivan S.; Adeyeye, Adekunle O.; Samarin, Sergey; Kostylev, Mikhail; Williams, Jim F.


We demonstrate experimentally a strong plasmon-assisted enhancement of the transverse magneto-optical Kerr effect in permalloy gratings. The enhanced transverse magneto-optical Kerr effect is accompanied by an increased grating reflectivity with the maximum of enhancement being correlated with plasmonic Fano resonances. This correlation was confirmed by an intuitive Fano model and also through full-vectorial optical simulations. Simultaneously high reflectivity and transverse magneto-optical...[Show more]
