Plasmon resonance enhancement of magneto-optic effects in garnets

Abstract

Enhancement of magneto-optic effects by strong electric fields induced by plasmon resonances in metallic nanoparticles placed on (or embedded into) garnets is discussed. Theoretical and computational results on excitation of plasmon resonances in such particles are reported and compared to available experimental data.

Magnetoplasmonics: Combining Magnetic and Plasmonic Functionalities

“…In fact, the main reason for the observed MO activity enhancement is the reduction of the refl ectivity, even though the MO component is also incremented, due to the enhancement of the EM fi eld inside the MO active layer. [119][120][121][122][123][124] For example, Figure 9. However, a simpler structural scenario may be faced if the MO component itself is dielectric in nature.…”

Enhanced Faraday rotation by a Fano resonance in substrate-free three-dimensional magnetoplasmonic structures

“…The electron spin is affected by the local electromagnetic field distribution in materials, and thus, the intensity of the MO effect can be controlled by changing the intensity of the local electromagnetic field. 41 As SPR has an obvious enhancement effect on the electromagnetic field, it is not a surprise that all the curves in Fig. 4g and h have a high FR value at 900–1000 nm, resulting from the increased function of the nanohole structure with the intensity of the local electromagnetic field.…”

Optical and magneto—optical properties of periodic Co double layer film

“…And unlike SPPs, LSPs can alter the sign of the Kerr angle, rather than only its magnitude. [7][8][9][10] In a patterned system, people usually study its properties at symmetric positions, but often neglect the situation at arbitrary positions. [11] However, if we study the properties at arbitrary positions, some novel phenomena might be unveiled.…”
