Magneto - Optics of freestanding Fe monolayers from first principles
The nonlinear magneto-optical Kerr-effect (NOLIMOKE) is determined for freestanding Fe monolayers with several in-plane structures from first principles. Based on the theory of nonlinear magneto-optics by Hübner and Benne-mann [Phys. Rev. B, 40, 5973 (1989)] we calculate the nonlinear susceptibil-ities of the monolayers using the ab initio FLAPW-method WIEN95 with the additional implementation ...
متن کاملNonlinear Magneto-Optics of Fe Monolayers from first principles: Structural dependence and spin-orbit coupling strength
We calculate the nonlinear magneto-optical response of free-standing fcc (001), (110) and (111) oriented Fe monolayers. The bandstructures are determined from first principles using a full-potential LAPW method with the additional implementation of spin-orbit coupling. The variation of the spinorbit coupling strength and the nonlinear magneto-optical spectra upon layer orientation are investiga...
متن کاملX-ray magneto-optics of lanthanide materials: principles and applications
Lanthanide metals are a particular class of magnetic materials in which the magnetic moments are carried mainly by the localized electrons of the 4f shell. They are frequently found in technically relevant systems, to achieve, e.g., high magnetic anisotropy. Magnetooptical methods in the x-ray range are well suited to study complex magnetic materials in an element-specific way. In this work, we...
متن کاملSuperconductor Magneto-optics and Theory
Some remarks are made on how to determine by magneto-optical imaging the electric currents flowing in a superconductor. The inversion problem is discussed how to compute these currents from the magnetic field measured in a planar magneto-optical indicator film positioned close to the conductor. Next, some geometries are listed for which the currents and magnetic fields can be computed from firs...
متن کاملFemtosecond spectrotemporal magneto-optics.
A new method to measure and analyze the time and spectrally resolved polarimetric response of magnetic materials is presented. It allows us to study the ultrafast magnetization dynamics of a CoPt3 ferromagnetic film. The analysis of the pump-induced rotation and ellipticity detected by a broad spectrum probe beam shows that magneto-optical signals predominantly reflect the spin dynamics in ferr...
