Observation of Magnetic-Anisotropy Crossover and High-Temperature Skyrmions in the Dirac Magnet Fe₃Ge with a Distorted Kagome Lattice. [PDF]

Adv Sci (Weinh)
A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

Magneto-optic Kerr effect in Gd20Co80 alloy

Semiconductor Physics, Quantum Electronics and Optoelectronics, 2022
The magneto-optical Kerr effect in Gd20Co80 alloy and cobalt thin films has been studied in a broad spectral range applying spectral ellipsometry experimental technique. The results of the experiments showed the complex nature of the complex Kerr angle dispersion curves. A quantum mechanical formalism for degenerate and non-degenerate Landau levels for

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.
