We report on how observation of the Goos−Hanchen (GH) shift can be used to spatially resolve the transverse magneto-optical Kerr effect (TMOKE) enhancement in all-nickel magnetoplasmonic crystals (MPCs). First, the excitation of surface plasmons in the MPCs leads to a 15.3 μm (18λ) GH shift. Then, in the presence of a transverse magnetic field, the modulation of the lateral spatial intensity distribution of the reflected light [TMOKE(x)], caused by the GH shift, reaches 4.7% in the experiment. The spatially resolved TMOKE(x) values are several times higher compared to those from conventional TMOKE measurements in the MPCs. The concept of the spatially resolved magneto-optical effects under GH shift can be further extended to other magnetophotonic nanodevices for additional enhancing magneto-optical effects, sensing, and light modulation applications.

“…The hybrid magneto-plasmonic (MP) materials combining noble and magnetic metals have been explored for enhanced SPR, so-called magneto-optical SPR (MOSPR) [1]. MOSPR sensors utilizing the transverse magneto-optical Kerr effect (TMOKE) have been exploited to date [2][3][4][5][6]. The TMOKE has the capability to adjust the intensity in reflected light when the applied magnetic field is oriented perpendicular to the plane of incident light.…”

We demonstrated the sensitivity enhancement for magneto-optical surface plasmon resonance (MOSPR) using noble/ferromagnetic metals multilayers. The proposed structure is based on the Kretschmann configuration in the transverse magneto-optical Kerr effect (TMOKE) methods with the FeCu superlattices (SLs) as magneto-plasmonic materials and gelatin as biomolecules analyte. The dielectric constants of the FeCu SLs are taken from first principles calculation, which is performed by using a full-potential linearized augmented plane wave (FLAPW) method. The important role of the hybridization process in optical transitions has been identified, and it can be modulated by adjusting the thickness of superlattices. The dependence of the reflectivity on the dielectric constant is performed by 4×4 transfer matrix methods. It is found that the minimum reflectivity directly influences the slope of angular spectra, with a maximum slope of TMOKE signal is 12.23/degree. The change in the gelatin’s refractive index results in TMOKE signal response, then the enhancement of the sensitivity of the MOSPR system can be shown.

“…Thus, the research on improving TMOKE intensity has been widely reported in recent years. Many optical resonant modes such as SPR, [3,[25][26][27][28] waveguide (WG) mode, [22,29] optical Tamm (OT) mode, [30] and Fabry-Perot effect [31] can be excited in designed nanostructures to enhance TMOKE. Comparatively, SPR and WG modes are more effective since their wave vectors can be nonreciprocally modified under the action of an external magnetic field, leading to a considerable enhancement of TMOKE.…”

Novel magneto‐optical (MO) properties can be actualized through well‐designed nanostructures, greatly improving the application value of MO effects. As only p‐polarized light can generate transverse magneto‐optical Kerr effect (TMOKE) in traditional MO materials, it is quite challenging and valuable to effectuate TMOKE under s‐polarization incidence at optical frequencies. The constructed nanopillar structures in this work can realize a clear TMOKE under both s‐polarization and p‐polarization incidences, as proved by experiments and simulations. Under s‐polarized incident light with an elevation angle of 45°, electric dipole resonance (EDR) and electric quadrupole resonance (EQR) are excited, resulting in the significant enhancement of TMOKE (five orders of magnitude higher than for the planar Co film). The intensity of s‐polarized TMOKE shows an increase with the enhancing diameter and height of the nanopillar structure. The amplitude of p‐polarized TMOKE is also appreciably increased due to the excitation of surface plasmon polaritons (SPPs) and localized surface plasmons (LSPs). Moreover, the Fe and Ni nanopillars display similar reflectivity and s‐polarized TMOKE behaviors in simulations. The s‐polarized TMOKE is unexpectedly observed in ferromagnetic metals for the first time, which builds up a considerable platform for the development and application of novel MO phenomena.
