Comment on “Ultrafast Demagnetization Measurements Using Extreme Ultraviolet Light: Comparison of Electronic and Magnetic Contributions”

Physical Review X, 2013
The time-resolved transverse magneto-optical Kerr effect using high-order harmonics is a very promising technique to study ultrafast magnetization dynamics. Recently, it was claimed that this technique was free of any nonmagnetic artifact.

Method to Suppress Polar Kerr Signal in a Longitudinal Magneto-Optic Kerr Effect Measurement

IEEE Magnetics Letters
The Magneto-Optical-Kerr-Effect (MOKE) is a convenient technique to study the magnetization of thin films. However, both polar and longitudinal MOKE responses contribute to the total Kerr response in a typical longitudinal MOKE measurement. Here, we present a simple optical technique to suppress the polar MOKE response in the oblique angle incidence by

Anisotropic optical and magneto-optical properties of antiferromagnetic Weyl semimetal Mn3Sn epitaxial thin films

APL Materials
Antiferromagnetic Weyl semimetal Mn3Sn exhibiting strong magneto-optical Kerr effect (MOKE) due to non-zero Berry curvature is attractive for spintronic and photonic device applications. Despite many reports on the anisotropic anomalous Hall effect (AHE),

Giant Enhancement of the Anomalous Transverse Magneto‐Optical Kerr Effect in a Magneto‐Optical Grating

Nanophotonics
ABSTRACT The anomalous transverse magneto‐optical Kerr effect (TMOKE) under s‐polarization is typically suppressed by symmetry constraints, leading to negligible signals. Here, we propose an indirect magneto‐optical (MO) coupling mechanism that originates from the spatially asymmetric near‐field distribution of resonant modes, rather ...
