Azimuthal rotation -- Cholesteric helix -- Conical boundary condition -- Conical surfaces -- Control voltages -- Controlled polarization -- Polarization characteristics -- Voltage dependence
Аннотация: The voltage dependences of polarization characteristics of light passed through the cholesteric layers with tangential-conical boundary conditions have been investigated. It has been shown that such layers allow turning the polarization azimuth more than 70˚ because of the unique untwisting effect of the cholesteric helix, due to free azimuthal rotation of the director on the substrate with conical anchoring. Optical cells under study have some advantages (low control voltage, smooth variation of polarization azimuth, simplicity of design) and can be used as an electrically controlled polarization rotator of white light.

Аннотация: he photoexcitation and photodissociation of diatomic molecules by intense pulse lasers has been the subject of extensive investigations over the past decades. However, the usually employed theoretical framework neglects the coupling between the molecular rotational angular momentum (R) and the angular momentum of the electrons projected onto the molecular axis Ω=Λ+Σ, which results in the known Λ-doubling phenomenon in high-resolution electronic spectra of diatomic molecules. While neglecting this coupling is an excellent approximation in the weak-field or perturbative regime owing to the large mass difference between the rotating atoms and the electrons, the approximation breaks down for intense laser pulses because of the repeated Rabi cycling of the electronic transitions, which can have a significant effect on the rotational degrees of freedom of the molecule. By correcting the transition dipole matrix elements and introducing angular basis sets based on Wigner D functions, the conventional theoretical treatment is generalized to a universal description valid for both the weak- and strong-field regimes. The theoretical treatment developed here is applied to the ∣1Σ› to ∣1Π› transitions in diatomic systems. Our results reveal that, for field intensities resulting in about one Rabi cycling for extreme ultraviolet or x-ray transitions, the theoretical predictions by the conventional theoretical frame need to be corrected when considering observables such as the molecular alignment and the angular distribution of the photofragments.

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: The Faraday effect (FE) was studied in Co-Sm-O composite films consisting of nanoparticles of metallic cobalt embedded in a samarium oxide dielectric matrix. The volume of the magnetic phase was similar to 60%. The FE spectral dependence for the condensates studied revealed a substantial change as compared to that for bulk cobalt samples, as well as for the films of nanocrystalline Co and CoSm films prepared in this study. An enhancement of the FE was also observed in the short-wavelength part of the optical spectrum. (c) 2005 Pleiades Publishing, Inc.

Аннотация: Magnetic susceptibility, electron paramagnetic resonance (EPR) and optical absorption have been studied in a glass system 20La(2)O(3)-22Al(2)O(3)-23B(2)O(3)-35(SiO2 + GeO2) with a part of La2O3 substituted by Gd2O3 in different concentrations. Positive Weiss constants have been found in more heavily doped glasses and ascribed to clustering of Gd3+ ions. Computer simulations of the EPR spectra show that the short-range ordering in the environment of the Gd3+ ions is well preserved. The relative distribution widths of the ligand coordinates are less than 2%. In the more heavily doped glasses the EPR spectra are superpositions of signals arising from isolated ions and ferromagnetic clusters. The increase of Gd3+ concentration is shown to change substantially the strong optical absorption edge while only small changes of f-f absorption band characteristics are observed. This difference is associated with the different effect of the Gd ion clustering on the mechanisms of the strong absorption in the ultraviolet region and the f-f absorption.

Аннотация: A new type of nanoparticle-containing glasses based on borate glasses co-doped with low contents of iron and larger radius elements, Dy, Tb, Gd, Ho, Er, Y, and Bi, is studied. Heat treatment of these glasses results in formation of magnetic nanoparticles, radically changing their physical properties. Transmission electron microscopy and synchrotron radiation-based techniques: x-ray diffraction, extended x-ray absorption fine structure, x-ray absorption near-edge structure, and small-angle x-ray scattering, show a broad distribution of nanoparticle sizes with characteristics depending on the treatment regime; a crystalline structure of these nanoparticles is detected in heat treated samples. Magnetic circular dichroism (MCD) studies of samples subjected to heat treatment as well as of maghemite, magnetite, and iron garnet allow to unambiguously assign the nanoparticle structure to maghemite, independently of co-dopant nature and of heat treatment regime used. Different features observed in the MCD spectra are related to different electron transitions in Fe3+ ions gathered in the nanoparticles. The static magnetization in heat treated samples has non-linear dependence on the magnetizing field with hysteresis. Zero-field cooled magnetization curves show that at higher temperatures the nanoparticles occur in superparamagnetic state with blocking temperatures above 100 K. Below ca. 20 K, a considerable contribution to both zero field-cooled and field-cooled magnetizations occurs from diluted paramagnetic ions. Variable-temperature electron magnetic resonance (EMR) studies unambiguously show that in as-prepared glasses paramagnetic ions are in diluted state and confirm the formation of magnetic nanoparticles already at earlier stages of heat treatment. Computer simulations of the EMR spectra corroborate the broad distribution of nanoparticle sizes found by "direct" techniques as well as superparamagnetic nanoparticle behaviour demonstrated in the magnetization studies.

Аннотация: We report high-resolution X-ray diffraction, muon-spin-rotation spectroscopic and specific heat measurements in the double spin-chains compound LiCu2O2. The X-ray diffraction results show that the crystal structure of LiCu2O2 is orthorhombic down to T = 10 K. Anisotropic line-broadening of the diffraction peaks is observed, indicating disorder along the spin chains. Muon-spin relaxation and specific heat measurements show that LiCu2O2 undergoes a phase transition to a magnetic ordered state at T-1 similar to 24 K. The specific heat data exhibits a second lambda -like peak at T-2 similar to 32.5 K, which increases with increasing magnetic field in a similar way to that found in spin-ladder compounds.

Аннотация: Co-Ti-O nanogranular films with different volume concentrations of a magnetic phase and Co/Ti-O layered structures with different numbers of layer pairs are studied by the magnetooptical Kerr effect. It is shown that, unlike the case of homogeneous metal films, the magnetooptical spectra of the nanogranular films exhibit resonance with a significant increase in the Kerr rotation angle in the wavelength range 500-700 nm. It is found that the Kerr rotation angle of the Co/Ti-O layer structures in the wavelength range 500-600 nm grows by an order of magnitude as compared to its value for ordinary Co films.

magnetic nanoparticles -- oxide glasses -- faraday rotation -- magnetic circular dichroism
Аннотация: Faraday rotation (FR) and magnetic circular dichroism (MCD) of nanocomposite structures based on potassium-aluminum-germanium-boron glasses co-doped with Fe and rare earth (RE) or Y+Bi oxides have been studied. Formation of magnetic nanoparticles as a result of the glass heat treatment ensures them magnetic and magneto-optical properties typical of magnetically ordered substances. At the same time, glasses keep transparence in visual spectral range owing to low paramagnetic oxides concentration. FR and MCD spectra of the heat treated glasses are shown to be very close to those of gamma-Fe(2)O(3) and practically independent of the RE element nature for the light wave energies lower than 22000 cm(-1). For higher energies, the MCD spectrum shape depends strongly an RE what evidences the different origin of magneto-optical effects in two spectral ranges.

Аннотация: Metallic nickel nanoparticles of various sizes are formed in a thin near-surface layer in an amorphous SiO2 matrix during 40-keV Ni+ ion implantation at a dose of (0.25-1.0) x 10(17) ions/cm(2). The micro-structure of the irradiated layer and the crystal structure, morphology, and sizes of nickel particles formed at various irradiation doses are studied by transmission electron microscopy and electron diffraction. The magnetooptical Faraday effect and the magnetic circular dichroism in an ensemble of nickel nanoparticles are studied in the optical range. The permittivity (epsilon) over cap tensor components are calculated for the implanted samples using an effective medium model with allowance for the results of magnetooptical measurements. The spectral dependences of the tensor (epsilon) over cap components are found to be strongly different from those of a continuous metallic nickel film. These differences are related to a disperse structure of the magnetic nickel phase and to a surface plasma resonance in the metal nanoparticles.

Аннотация: The influence of the orientational order of molecules in a nematic liquid crystal on the mean value ?? and anisotropy ?? of the molecular polarizability has been studied in the framework of the molecular statistical approach with allowance for the perturbation of the electronic structure of molecules due to the change in the conformation of their aromatic core and intermolecular interactions. Experimental dependences of ?? and ?? on the molecular orientational order parameter S have been derived, and their specific features for the known objects have been explained. The possibility of separating the contributions of opposite signs to the dependence ??(S) due to the change in the conformation of molecules and intermolecular interactions has been shown using nematic MBBA as an example. © 2014 Pleiades Publishing, Ltd.
