Magneto-optical Kerr Effect in Ferroelectric Antiferromagnetic Two-Dimensional Heterostructures

ACS Applied Materials & Interfaces, 2023
We study the magneto-optical Kerr effect (MOKE) of the two-dimensional heterostructure CrI3/In2Se3/CrI3 by using density functional theory calculations and symmetry analysis. The spontaneous polarization in the In2Se3 ferroelectric layer and the antiferromagnetic ordering in CrI3 layers break the mirror symmetry and the timereversal symmetry, thus ...

Waveguide-Plasmon Polaritons Enhance Transverse Magneto-Optical Kerr Effect [PDF]

Physical Review X, 2013
Magneto-optical effects in ferrimagnetic or ferromagnetic materials are usually too weak for potential applications. The transverse magneto-optical Kerr effect (TMOKE) in ferromagnetic films is typically on the order of 0.1%.

Gate-Controllable Magneto-optic Kerr Effect in Layered Collinear Antiferromagnets

Physical Review Letters, 2016
Using symmetry arguments and a tight-binding model, we show that for layered collinear anti- ferromagnets, magneto-optic effects can be generated and manipulated by controlling crystal symmetries through a gate voltage. This provides a promising route for electric field manipulation of the magneto-optic effects without modifying the underlying magnetic

Magneto-optical Kerr effect in resonant subwavelength nanowire gratings

New Journal of Physics, 2014
Periodic arrays of nanorods can present a resonant response at specific geometric conditions. We use a multiple scattering approach to analyze the optical response of subwavelength nanowire gratings made of arbitrary anisotropic materials.

Inverse transverse magneto-optical Kerr effect [PDF]

Physical Review B, 2012
It is demonstrated that a static in-plane magnetic field is generated in a ferromagnetic film by p-polarised light obliquely incident on the film. This phenomenon can be called inverse transverse magneto-optical Kerr effect. The femtosecond laser pulse of peak intensity of 500 W/ m2 generates in nickel an effective magnetic field of about 100 Oe.

Large ultrafast-modulated Voigt effect in noncollinear antiferromagnet Mn3Sn

Nature Communications, 2021
Mn3Sn is an anti-ferromagnetic material which displays a large magneto-optical Kerr effect, despite lacking a ferromagnetic moment. Here, the authors show that likewise, Mn3Sn, also presents a particularly large magneto-optical Voigt signal, with a ...

Anisotropic Third-Order Magneto-Optical Kerr Effect [PDF]

7th Joint MMM-Intermag Conference. Abstracts (Cat. No.98CH36275), 1998
The magnitude of the polar magneto-optical Kerr effect in reflection from thick iron epitaxial films is experimentally found to strongly depend on the crystallographic orientation of the film, with variations of more than 20%. Similar results are obtained on the (001) and (110) faces of a bulk Fe crystal.

Ultrafast element- and depth-resolved magnetization dynamics probed by transverse magneto-optical Kerr effect spectroscopy in the soft x-ray range

Physical Review Research, 2022
We report on time- and angle-resolved transverse magneto-optical Kerr effect spectroscopy in the soft x-ray range that, by analysis via polarization-dependent magnetic scattering simulations, allows us to determine the spatiotemporal and element-specific

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
