Аннотация: The influence of quasilocal vibrations on the far-infrared spectra of glasses is investigated under the supposition that the quasilocal vibrations are directly inactive in the attenuation. It is shown that taking into account phonon-quasilocal-vibration coupling and both medium- and short-range structure of the inhomogeneities of a photon-phonon coupling parameter can give rise to an attenuation curve similar to one observed for a-SiO2 and related materials.

Аннотация: We consider a typical semiconductor resonant tunnelling GaAs/AlGaAs/GaAs nanostructure which forms a double-barrier potential with quasienergy levels corresponding to transition frequencies in the infrared and microwave regions. Two types of dynamical perturbation of the heterostructure in the form V-1(x, t) = V(1)x cos Omega t and V-2(t) = V-2 cos Omega t are considered. We analyse numerically a reconstruction of the electron transmission through the heterostructure and the current-voltage characteristics (IVC) under the influence of these dynamical perturbations. Both weak and strong perturbations are considered. We investigate the dependences of the transmission on the electron energy and the frequency of the external field with the main accent on the case where a frequency of the perturbation is tuned to a transition between quasienergies of the double-barrier structure. it is found that these resonant phenomena give rise to new peaks and dips in the IVC. In particular, it is shown that the dipole type of perturbation V-1(x, t) gives rise to a Rabi splitting of the transmission peaks and under certain conditions to a Rabi splining of the IVC peaks and dips. We demonstrate that dynamical perturbation may induce a direct current opposite to the direction of the applied voltage, and that this phenomenon takes the form of a sharp dip which has a resonant origin. It is observed that the dipole type of perturbation V-1(x, t) of laser radiation is more effective for tuning the IVC than the first perturbation V-2(t). Also absorption and emission of energy by an electron transmitted through the DBRTS are considered.

Аннотация: The electronic structures of all the possible isomers of endohedral and exohedral C(60) fullerene complexes with two lithium atoms are theoretically investigated. It is found that the electronic structures of these compounds are characterized by an impurity filled-level state determining the band gap. The location of the impurity state and, correspondingly, the band gap of the exohedral fullerene complexes depend on the coordination mode and the distance between the alkali metal ions. A similar dependence is observed for the total energy of the exohedral fullerene complex under investigation. (C) 2001 MAIK "Nauka/ Interperiodica".

Аннотация: Formation of incommensurate three-dimensional magnetic order below T* similar to 10 K in CuB2O4 is explained on the basis of strong correlation between the holes and localized spins. The Kondo lattice model is analysed for the case where spin polarons are the elementary excitations. The origin of the low-temperature specific heat maximum at T similar to 5 K is associated with a displacement of the polaron band bottom. A set of anomalies in the temperature dependence of the conductivity, shift of the optical conductivity maximum in the range of energies 0.02-0.12 eV and decreasing of the infrared absorption intensity is predicted.

Аннотация: A number of new peaks close to the previously predicted energies of virtual electronic states [S.G. Ovchinnikov and V.N. Zabluda, Zh. Eksp. Teor. Fiz. 125, 150 (2004) [JETP 98, 135 (2004)]] have been observed in the absorption spectra of FeBO3 single crystals in the infrared range. The 0.27-eV peak was absent in the scheme presented in the work cited above and, to explain it, a multielectron theory taking into account the (2) T (2) low-spin term of the Fe3+ ion has been developed.

Аннотация: High-resolution polarized optical absorption spectra of PrFe3(BO3)(4) in the paramagnetic and antiferromagnetic phases are reported. The measured energies of the crystal-field (CF) levels within the 4f(2) configuration of Pr3+ in the paramagnetic PrFe3(BO3)(4) are described by the CF model that involves the 4f(2)/4f5d and 4f(2)/4f6p configuration interactions. Ordering of Fe spins along the crystalline c axis below T-N=32 K is confirmed by the analysis of the spectra of Er3+ introduced as a probe into PrFe3(BO3)(4). To account for the observed changes in the optical spectra of Pr3+ at temperatures below T-N, in particular, for the shift of the CF levels, splitting of the CF doublets, and the appearance of forbidden lines, the Pr-Fe exchange Hamiltonian defined by seven parameters is considered. The theoretical approach has been tested by calculating the temperature dependence of the magnetic susceptibility. A good agreement between theory and optical and magnetic experimental data is found demonstrating the validity of the model used. The obtained results confirm that the model of the iron dimers inside the spiral chains of Fe3+(O2-)(6) octahedrons introduced by us earlier for NdFe3(BO3)(4) and modified in the present work may serve as a basis for analyzing the low-temperature properties of other rare-earth iron borates.
