Spin polarized conduction and valence band states in GdN

AbstractOptical transmission spectra are collected in the ferromagnetic state of GdN at various temperatures. The temperature dependent extinction coefficient extracted from the transmission measurements show that the conduction and valence band states are spin polarized. The results confirm the LSDA+U estimates of the energy gap associated with the majority/minority-spins and also the magnitude of the spin splitting.

Diffraction Patterns

The results of investigation of optical transmission spectra and X-ray diffraction of thin In2O3 films deposited by dc-magnetron sputtering on Al2O3 (012) substrates are presented. The diffraction patterns exhibit the presents of the (222) reflex of cubic In2O3. Its position shifts from 30.3 to 30.6°, with a decrease in the film thickness. There was also a decrease in the half-width of this reflex by a decrease in the deposition time, which may indicate an increase in the crystallite size of the film material. According to the optical transmission measurements, the presence of a transition layer with the band gap of 1.39 eV and about of 40 nm thickness was established at the interface between the film and substrate. The properties of this layer are independent of the deposition time.

Principal Possibility

Principal possibility of the using of chalcogenide glasses (on the example of Ge18As18Se64) as active media for temperature sensors is considered in this work. Differential scanning calorimetry testing of the investigated glasses shown that 2 years of natural storage does not lead to the drift of their DSC-parameters (glass transition temperature and endothermic peak area). Investigation of the temperature dependence of optical transmission spectra shows the linear character of optical band-gap changes with a temperature. Temperature sensitivity index β for Ge18As18Se64 is estimated to be equal to the ~1.2·10-3 eV/°C.
