(a) The AFM image of the all-nickel magneto-plasmonic grating. Black bar is equal to 1 μm; (b) TMOKE spectra of the one-dimensional magneto-plasmonic grating (circles) and the reference plain nickel film (dashed curve). The solid line shows the reflection spectrum of the grating. Reproduced from [50] with permission by AIP Publishing LLC, Copyright 2010.
