Enhancement of magneto-optical Kerr effects

Journal of Applied Physics, 1990
A general expression for the magneto-optical polar Kerr effect is given for a bilayered configuration in which the optical constants of the two media differ. The equation shows that a giant enhancement of the Kerr effect in magneto-optical/metallic bilayers can be expected if the dielectric constants of the two materials are low or are matched well to ...

Enhancing magneto-optic effects in two-dimensional magnets by thin-film interference

AIP Advances, 2021
The magneto-optic Kerr effect is a powerful tool for measuring magnetism in thin films at microscopic scales, as was recently demonstrated by the major role it played in the discovery of two-dimensional (2D) ferromagnetism in monolayer CrI3 and Cr2Ge2Te6.

Control over magneto-optical plasmon rotation with Doppler broadening and cross-Kerr non-linearity

Results in Physics, 2023
We investigate the impacts of cross-Kerr non-linearity and Doppler broadening on the magneto-optical rotation (MOR) induced in surface plasmon polaritons (SPPs) located at the interface of a metalic medium and a 4-level atomic system.

Influence of the magnetic field on the plasmonic properties of transparent Ni anti-dot arrays [PDF]

, 2012
Extraordinary optical transmission is observed due to the excitation of surface plasmon polaritons (SPPs) in 2-Dimensional hexagonal anti-dot patterns of pure Ni thin films, grown on sapphire substrates. A strong enhancement of the polar Kerr rotation is
