Light Reflection Band between the Zeeman Lines in Diluted Magnetic Semiconductors

Complex dielectric constant of Cd0.8SMn0.2Te crystals near the fundamental absorption edge

“…In this case the summation accounts for transitions between all relevant pairs of the Zeeman levels. The complex reflection coefficient of the p-polarized wave incident on the crystal from the air at the angle ϑ [13] can be expressed as…”

Non-reciprocal reflection band in CdMnTe

“…An oscillator model applied to electronic transitions at the Brillouin zone center has been found to agree with experimental non-reciprocity peaks related to the Zeeman-splitted excitonic lines [4]. However, the Lorentz oscillator model failed to describe the band of non-reciprocal reflection manifesting itself between the Zeeman lines.…”

“…It has been found in the case of oblique incidence of p-polarized light, that the light reflection from Cd 1−x Mn x Te single crystals is non-reciprocal in the presence of a steady magnetic field transverse to the plane of incidence, i.e. in the extraordinary Voigt configuration [4]. In this case, the light wave electric field in DMS is elliptically polarized in the plane of incidence, i.e.…”

Optical Properties of Cd1-xMnxTe Crystals near Fundamental Absorption Edge in Transverse Magnetic Fields

“…The complex reflection coefficient is calculated assuming the surface of the sample to be a flat boundary between two semi-infinite media [6].…”
