Wide band enhancement of transverse magneto-optic Kerr effect in magnetite

Transverse magneto-optical Kerr effect (TMOKE) is known to be an effective tool for external magnetic field control of optical properties of magnetoplasmonic crystals. In some applications there is a demand for the pronounced TMOKE in the wide wavelength range. In this work we experimentally and the...

Description
Summary:Transverse magneto-optical Kerr effect (TMOKE) is known to be an effective tool for external magnetic field control of optical properties of magnetoplasmonic crystals. In some applications there is a demand for the pronounced TMOKE in the wide wavelength range. In this work we experimentally and theoretically demonstrate that a magnetite based magnetoplasmnic crystal exhibit a multiple wide band enhancement of TMOKE response in transmission compared to a plain magnetite film without metal. Our RCWA calculations are in good agreement with experimental results.
