Magneto-ellipsometry as a powerful technique for investigating magneto-optical structures properties

Magneto-Optical properties of GaP single crystal

The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...

Magneto-optical properties of multilayer graphene

The magneto-optical absorption properties of graphene multilayers are theoretically studied. It is shown that the spectrum can be decomposed into sub-components effectively identical to the monolayer or bilayer graphene, allowing us to understand the spectrum systematically as a function of the layer number. Oddlayered graphenes always exhibit absorption peaks which shifts in proportion to B, w...

Magneto-optical properties of MnBiAl thin films

Magneto-optical properties of HgTe-CdTe superlattices.

We present a comprehensive theoretical formulation for magneto-optical properties in narrow-band-gap and zero-band-gap Hg Te-CdTe superlattices. It is found to be crucial that the details of the unique band structure be taken into account in full generality. Statistical factors also play a dominant role in the magneto-optical properties, since the location of the Fermi level determines which of...

Magneto-optical properties of nickel nanowire arrays

We report on the magneto-optical properties of hexagonally arranged Ni nanowires embedded in anodic alumina templates. Due to the nanowire geometry, these samples show different response depending on the polarization orientation of the incident light, which leads to a high anisotropy of both their optical and magneto-optical properties. A strong increase of the magneto-optical activity is clear...
