Polarization transformation and destructive interference on subwavelength magnetic domains in magneto-plasmonic systems

Abstract We demonstrate magneto-optical (MO) polarization transformation due to surface plasmons in CoPt perpendicular magnetic films in the polar Kerr geometry. An extraordinary Kerr rotation angle (θ K =  ± 88.9°) that almost reaches the upper limit of polarization is produced in the attenuated to...
