Scanning electron microscopy image of the sample surface after evaporation of Ni. The image depicts the stage of the lift off of the self-assembled polystyrene beads, which leaves behind an antidot patterned film of Ni. The resulting sample has an average pitch size of a = 450 nm and hole diameter of d = 300 nm.
(a) Experimental transmission and polar Kerr rotation spectra for the Ni antidot structure of Fig. 1. Kerr values were obtained with the film at the saturated state (B = 1.7 T). The transmission curve has been corrected for the substrate. (b) Calculated transmission and polar Kerr rotation spectra. (c) Calculated dispersion relation of the Bragg plasmons both for the Ni/air interface and Ni/sapphire interface. The vertical line is drawn at and the horizontal line at 660 nm.
(a) Reflectivity (black dot-line, left axis) and the TMOKE (red square-line, right axis). The TMOKE signal presents a clear shift and enhancement. (b) Reflectivity in the angular range of the minimum in the direction for the two directions of the magnetization.
(a) Calculated reflectivity in the angular range of the minimum in the direction (black line, left axis) and the TMOKE (red line, right axis). (b) Calculated reflectivity (right panel) and TMOKE (left panel) in the same angular range as in (a) along different in-plane directions, going from the (0°) to the (30°) along the KM direction.
