Magneto-plasmonic crystals formed by a plasmonic layer near a magnetic layer. In this paper, the optimal thicknesses of magneto-plasmonic crystal Au/Ni for enhancement of magneto-optical Kerr effect (MOKE) have been investigated theoretically. In Glass/Au/Ni structure gold and nickel used as plasmonic and magnetic materials respectively. The maximum Kerr signal 16.46 degree was obtained by 9 nm thick film of gold and 10 nm thick of nickel layer in Glass/Au/Ni structure at 47 degree of incident angle. Also, the maximum Kerr signal 24.17 degree was obtained by 7 nm thickness of Gold layer and 13 nm thickness of Nickel layer in Glass/Ni/Au structure at 48 degree of incident angle.
Keywords: Magneto-optical Kerr effect, Surface plasmon polariton, Magneto plasmonic
