Abstract

The work is devoted to the development of magnetic field sensor based on magnetoplasmonic crystal and demonstrates the results of studying spectral and field dependences of reflectivity and transverse magneto-optical Kerr effect (TMOKE) geometry. It is shown, that magneto-optical properties of studied samples non monotonously change due to the different contributions of surface plasmon-polaritons excitation, magnetic and optical properties into the TMOKE enhancement process. Presented samples allow one to achieve the sensitivity of tens μOe to the DC magnetic field magnitude in an area of 1 mm2 and perform a mapping of external uniaxial magnetic field without moving the MPlC.
