We show that the enhancement of the transverse magneto-optical Kerr effect of a smooth magnetic dielectric film covered by a noble metal grating, is strongly dependent on the precise geometry of this grating. Up till now this magnetoplasmonic enhancement was solely attributed to a nonreciprocal shift of the dispersion of the surface plasmon polariton resonances at the interface with the magneti...

We have performed magneto-optical Kerr spectroscopy measurements on intercalated transition-metal dichalcogenide Fe0.25TaS2 in the polar Kerr geometry as a function of temperature, magnetic field, and wavelength. The Kerr angle exhibits pronounced peaks at ∼775 nm (1.6 eV) and ∼515 nm (2.4 eV), which we attribute to spin-dependent interband optical transitions arising from states in the vicinit...

Technological advances in sensor designs (e.g. increased sensitivity) may be achieved by combining plasmonic and magneto-optical materials, thus leading to magneto-plasmonic systems. Noble metal-ferromagnetic systems, such as Au/Co/Au trilayers and Au/FePd bilayers, are candidates for magneto-plasmonic systems, where surface plasmon polaritons (SPPs) may be modulated by externally applied magne...

Structuring metallic and magnetic materials on subwavelength scales allows for extreme confinement and a versatile design of electromagnetic field modes. This may be used, for example, to enhance magneto-optical responses, to control plasmonic systems using a magnetic field, or to tailor magneto-optical properties of individual nanostructures. Here we show that periodic rectangular arrays of ma...

We calculate the nonlinear magneto-optical response of free-standing fcc (001), (110) and (111) oriented Fe monolayers. The bandstructures are determined from first principles using a full-potential LAPW method with the additional implementation of spin-orbit coupling. The variation of the spinorbit coupling strength and the nonlinear magneto-optical spectra upon layer orientation are investiga...
