Controlling the Transverse Magneto-Optical Kerr Effect in Cr/NiFe Bilayer Thin Films by Changing the Thicknesses of the Cr Layer [PDF]

Nanomaterials, 2020
Here, we demonstrate the impact of ferromagnetic layer coating on controlling the magneto-optical response. We found that the transverse magneto-optical Kerr effect (TMOKE) signal and TMOKE hysteresis loops of Ni80Fe20 thin layers coated with a Cr layer ...

TMOKE as efficient tool for the magneto-optic analysis of ultra-thin magnetic films [PDF]

Applied Physics Letters, 2018
Ultra-thin magnetic dielectric films are of prime importance due to their applications for nanophotonics and spintronics. Here, we propose an efficient method for the magneto-optical investigation of ultra-thin magnetic films which allows one to access their state of magnetization and magneto-optical properties.

Bulk Plasmon Polariton Modes in Hyperbolic Metamaterials for Giant Enhancement of the Transverse Magneto-Optical Kerr Effect [PDF]

Molecules, 2022
We demonstrate a concept for the giant enhancement of the transverse magneto-optical Kerr effect (TMOKE) using bulk plasmon polariton (BPP) modes in non-magnetic multilayer hyperbolic metamaterials (HMMs).

Nanophotonic devices based on magneto-optical materials: recent developments and applications. [PDF]

Nanophotonics, 2022
Abstract Interaction between light and magnetism in magneto‐optical (MO) nanophotonic devices has been actively studied in the past few years. The recent development of MO all‐dielectric resonators and metasurfaces has led to the emergence of various novel MO phenomena that were not observed in their bulk counterparts.

Optimization of Magnetoplasmonic ε-Near-Zero Nanostructures Using a Genetic Algorithm [PDF]

Sensors, 2022
Magnetoplasmonic permittivity-near-zero (ε-near-zero) nanostructures hold promise for novel highly integrated (bio)sensing devices. These platforms merge the high-resolution sensing from the magnetoplasmonic approach with the ε-near-zero-based light-to ...

Two-dimensional array of iron-garnet nanocylinders supporting localized and lattice modes for the broadband boosted magneto-optics. [PDF]

Nanophotonics, 2022
Abstract We demonstrate a novel all‐dielectric magnetophotonic structure that consists of two‐dimensional arrays of bismuth substituted iron‐garnet nanocylinders supporting both localized (Fabry–Perot‐like) and lattice (guided‐like) optical modes. Simultaneous excitation of the two kinds of modes provides a significant enhancement of the Faraday effect
