چکیده

The magneto-optical properties of cesium vapor near a glass surface have been studied by using selective reflection. We have observed sub-Doppler structures in the magnetorotation and magnetic circular dichroism spectra. The spectral narrowing can be explained by the transient polarization behavior of cesium atoms due to wall collisions. A simple model, which takes atom-wall collisions and the mixing of hyperfine levels by the magnetic field into account, gives a good qualitative description of the observed spectra. Small discrepancies are likely to be due to long-range atom-surface interactions.

Magnetic anisotropic effects and electronic correlations in MnBi ferromagnet

The electronic structure and numerous magnetic properties of MnBi magnetic systems are investigated using local spin density approximation (LSDA) with on-cite Coulomb correlations (LSDA+U ) included. We show that the inclusion of Coulomb correlations provides a much better description of equilibrium magnetic moments on Mn atoms as well as the magnetic anisotropy energy behavior with temperature...

Electrically controlled terahertz magneto-optical phenomena in continuous and patterned graphene

The magnetic circular dichroism and the Faraday rotation are the fundamental phenomena of great practical importance arising from the breaking of the time reversal symmetry by a magnetic field. In most materials, the strength and the sign of these effects can be only controlled by the field value and its orientation. Furthermore, the terahertz range is lacking materials having the ability to af...

Magneto-optical observation of a magnetically induced ” domain spin-flop ” in a cubic antiferromagnet : KNiF3

2014 We have observed a large change in the field dependence of the magneto-optical spectra of cubic KNiF3 at a low magnetic field. This phenomenon, which is being reported for the first time, is compared to the well-known spin-flop occurring in uniaxial antiferromagnets. Spectroscopic calculations allow us to attribute the magnetic circular dichroism signals that have been observed below and a...

Nuclear spin circular dichroism.

Recent years have witnessed a growing interest in magneto-optic spectroscopy techniques that use nuclear magnetization as the source of the magnetic field. Here we present a formulation of magnetic circular dichroism (CD) due to magnetically polarized nuclei, nuclear spin-induced CD (NSCD), in molecules. The NSCD ellipticity and nuclear spin-induced optical rotation (NSOR) angle correspond to t...
