Enhanced Transverse Magneto-Optical Kerr Effect in Magnetoplasmonic Crystals for the Design of Highly Sensitive Plasmonic (Bio)sensing Platforms. [PDF]
ACS Omega, 2017 We propose a highly sensitive sensor based on enhancing the transversal magneto-optical Kerr effect (TMOKE) through excitation of surface plasmon resonances in a novel and simple architecture, which consists of a metal grating on a metal magneto-optical ...

Giant optical activity and Kerr effect in type-I and type-II Weyl semimetals [PDF]
Physical review B, 2019 We explore optical activity in thin films and bulk of type-I and type II Weyl semimetals (WSM), and demonstrate the existence of a giant Kerr effect in both.

Comparing the anomalous Hall effect and the magneto-optical Kerr effect through antiferromagnetic phase transitions in Mn3Sn [PDF]
Applied Physics Letters, 2019 In the non-collinear antiferromagnet Mn3Sn, we compare simultaneous measurements of the anomalous Hall effect (AHE) and the magneto-optical Kerr effect (MOKE) through two magnetic phase transitions: the high-temperature paramagnetic/antiferromagnetic (AF)

The phase shift induced by a single atom in free space [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In this article we theoretically study the phase shift a single atom imprints onto a coherent state light beam in free space. The calculations are performed in a semiclassical framework.

Magneto-optical Kerr effect in spin split two-dimensional massive Dirac materials [PDF]
2D Materials, 2019 Two-dimensional (2D) massive Dirac electrons possess a finite Berry curvature, with Chern number 1/2, that entails both a quantized dc Hall response and a subgap full-quarter Kerr rotation.

Faraday and Kerr Effects in Right and Left-Handed Films and Layered Materials
Reviews on Advanced Materials Science, 2020 In the present work, we study the rotations of the polarization of light propagating in right and left-handed films and layered structures. Through the use of complex values representing the rotations we analyze the transmission (Faraday effect) and ...
