“…The geometry is Voigt configuration in cyclotron resonance-inactive mode, in which applied magnetic field is parallel to the plane of incidence and perpendicular to the propagation direction of the SPPs. The magneto-plasmonic effect was evaluated from the reflectivity curves obtained from the ATR measurement on the basis of the normalized reflectivity change in a magnetic field using the following formula 9,12,14,30,31) [ ( )-( )] ( )…”

“…Magneto-plasmonic effect is a promising phenomenon connected surface plasmonic properties with magnetic properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] for a future magnetic sensing application. [19][20][21][22][23][24] The surface plasmon polaritons (SPPs), which are electromagnetic waves propagating at an interface between a metal and a dielectric material, are super-sensitive to changes in the dielectric constants of the interfacial materials.…”

“…Three types of magneto-plasmonic materials have been reported as follows; (1) all metallic tri-layer or multilayer films of a noble metal/a magnetic metal/a noble metal, such as Au/Co/Au, 1,4,5) Ag/Co/Ag, 2,18) Au/Fe/Au, 3,7) Ag/CoFeAlSi/Ag films 14) and so on, (2) a magnetic ceramic/a noble metal bilayer film, such as Au/MFe 2 O 4 (M=Zn, Ni, Co) 10,12,13) and Ag/Bi 3 Fe 5 O 12 films, 17) and (3) single layer films with binary non-solid-solution metals, [25][26][27][28] such as Ag-Co, 9,11,16) Ag-Fe, 11) and Ag-Ni films. 15) The excitation condition of the SPPs is strongly related to the thicknesses of whole and each metallic layers, so it is difficult to control magnetic and plasmonic properties independently in all metallic tri-layer or multilayer films.…”

Annealing temperature dependence of the Ag–Co single layer films on the magneto-plasmonic effect was investigated for the future magnetic sensing applications. The findings are as follows; (1) Co grains can be clearly observed in the film annealed at 500 °C in the Ag–Co films, but cannot be observed in the both films as deposited and annealed at 300 °C, (2) all Ag–Co single layer films show magnetic hysteresis curves, (3) saturation field of the Ag–Co films annealed at 300 °C is smallest in the measured samples, and (4) magneto-plasmonic effects of the Ag–Co single layer films as a function of annealing temperature have a local maximum at annealing temperature of 300 °C. These facts imply that the Ag–Co film with Co grains of optimal size for the magneto-plasmonic effect is satisfied both small saturation field and large Co grain density.
