Quadratic magneto-optical Kerr effect in Co2MnSi

Journal of Applied Physics, 2011
Quadratic magneto-optical Kerr effects (QMOKE) are investigated in epitaxial Co2MnSi thin films as a function of the post-deposition annealing temperature. We determine the amplitude of the QMOKE signal for different annealing temperatures, which provide various degrees of L21 crystal ordering, as manifested by X-ray diffraction.

The magneto-optical Kerr effect of trilayer

Journal of Applied Physics, 1992
In this paper the magneto-optical polar Kerr rotation spectra of trilayers Fe/Ag/Cu, Fe/Cu/Ag, Fe/Au/Cu, and Fe/Cu/Au were measured and calculated. The experimental results coincided well with the calculated results. It was found that for trilayers Fe/Cu/Ag and Fe/Ag/Cu, with a 100 Å thickness of the top Fe layer, there were two Kerr rotation peaks in ...

Magneto-Optics Kerr Effect Instrumentation

2015
Progress in science technology requires new tools to study novel magnetic thin films surfaces and interfaces. Magneto-Optic Kerr Effect (MOKE) instrument is an ideal tool to study nanometric magnetic thin films. MOKE instrument was built to study properties of epitaxial nanometric thin films deposited using magnetron sputtering system. The objective of

Surface Magneto-Optic Kerr Effect

2018
Surface magneto-optic Kerr effect (SMOKE) is based on magnetic circular dichroism (MCD), where the absorption for right and left circular polarized light is different because electronic states are split due to exchange interaction and spin–orbit coupling (Qui and Bader in Rev Sci Instrum 71:1243, 2000 [1]).

The Kerr magneto-optic effect (1876–1976)

Physica B+C, 1977
Abstract A discussion is given of the historical background of the Kerr magneto-optic effect as well as of details of the original experiments leading to its discovery. Kerr's scientific achievements are described in the context of research endeavour of the nineteenth century.

Nonlinear magneto-optical Kerr effect on a nickel surface

Physical Review B, 1989
Nonlinear surface optics is being developed as a useful new tool in surface science. In this work, we calculate the second-order magneto-optical response function in order to determine the nonlinear magneto-optical Kerr effect. This is applied to the surface of ferromagnetic nickel.

Magneto-optical Kerr effect measurements with uniform laser profiles

Journal of Applied Physics, 2007
The probability distribution of the amplitude (ΔM) of Barkhausen jumps during magnetization reversal in thin films can be measured with optical techniques since each jump produces a variation (ΔI) of the laser beam intensity used to probe magnetization.

Magneto-optical Kerr effect in bilayer structures

The European Physical Journal B, 2000
This paper describes the magneto-optical effects and the reflectivity behaviors of bilayers based on magnetic and isotropic (MgF2)/anisotropic (TiO2) layers under the condition of total internal reflection. In the framework of Green's dyadic technique, we show accurately the optical properties of anisotropic layers deposited on a substrate.

Magneto-optic Kerr effect in a slab waveguide

Journal of Applied Physics, 2001
A theoretical and numerical investigation of the magneto-optic Kerr effect in a slab optical waveguide bounded on one side by a thin magnetic film is considered. The output power has been determined as a function of the input polarization angle, output analyzer angle, thickness of the intermediate cladding layer, and the length of the magnetic film. It

Magneto-optical Kerr effect in corrugated magnetoplasmonic heterostructures

Journal of the Optical Society of America B, 2013
We performed a detailed theoretical study of the magneto-optical polar Kerr effect in magnetoplasmonic heterostructures consisting of a plasmonic film and a ferromagnetic layer with a corrugated top surface. Explicit analytical expressions allowing us to calculate the modifications of the polar Kerr effect in dependence on the thickness of the ...
