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.

Intensities f-f transitions in Pr3+ and Dy3+ in glasses in the near-IR spectral range / I. S. Edelman [et al.] // Phys. Solid State. - 2001. - Vol. 43, Is. 6. - P. 1037-1042, DOI 10.1134/1.1378142. - Cited References: 21 . - ISSN 1063-7834

OXIDE GLASSES
Аннотация: The absorption spectra of Pr3+ and Dy3+ ions in three glass matrices (SiO2-P2O5-GeO2, Al2O3-B2O3-SiO2, and LiB3O5) are thoroughly studied in the near-IR spectral range (4600-14 300 cm(-1)). The temperature dependences of the intensity, the width, and the location of the absorption bands observed are investigated for the first time. It is shown that the f-f transitions in the studied glasses ate allowed by static odd distortions in the environment of the rare-earth ions and these distortions decrease with an increase in temperature. A comparative analysis of the absorption band parameters and their temperature behavior in different materials makes it possible to determine the differences in magnitudes, symmetries, and dispersions of the distortions in the nearest environment of rare-earth ions in different glasses.

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: Magnetic susceptibility, electron paramagnetic resonance (EPR), and optical properties 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 the more heavily doped glasses and ascribed to clustering of Gd3+ ions. Two magnetic phase transitions at 55 and 12 K were detected and ascribed, respectively, to ferromagnetic and antiferromagnetic clusters containing Gd ions. The overall shape of the EPR spectra shows the presence of clustering at the higher Gd contents. At low temperatures the cluster-related resonance signal is altered in shape, indicating an onset of magnetic anisotropy field. This signal is convincingly fitted to superparamagnetic resonance arising from ferromagnetic nanoparticles. The clustering, depending on the Gd concentration, correlates with a significant shift to lower energies of the strong optical absorption band edge, ascribed to a charge transfer transition between Gd ions. A nonmonotonous change of refractive index with the increase of the Gd content indicates changes in the glass matrix and in Gd cluster structure.

Аннотация: For the first time the problem of determining real composition and structure of manganese ferrite nanoparticles dispersed borate glasses is solved using differentiating dissolution and high-resolution X-ray electron microscopy techniques. For the first time the nanosize effect of aluminum incorporation in manganese ferrite composition is experimentally shown, thus directly confirming the hypothesis of Al participation in exchange interaction between paramagnetic Fe and Mn ions as diamagnetic diluter.

Аннотация: In this Reply we show that, contrary to the suggestion of Dubroca, Hack, and Hummel (DHH), the feature observed at ca. 55 K in the magnetic susceptibility of gadolinium-containing oxide glasses [as in our earlier paper, Kliava Phys. Rev. B 71, 104406 (2005)] cannot be due to a magnetic transition in oxygen contaminant. In support of this statement, we supply transformed data at low Gd content as well as magnetization curves for a series of glasses containing dysprosium oxide measured with the same superconducting quantum interference device as in our earlier paper. In all these cases the feature in question is absent. Thus, our previous assignment of the 55 K feature to a paramagnetic-to-ferromagnetic transition in Gd clusters in the glass remains the only one consistent with the experimental results.

Аннотация: Unique properties of the potassium–aluminum–boron glasses doped with low concentrations of MnO and Fe2O3 to make them magnetically ordered and optically transparent in the IR and visible ranges are due to the formation of nanoparticles of a cubic ferrite. Assembling and properties of nanosized ferrite particles in the glasses have been investigated by X-ray diffraction, differential dissolution analysis, high-resolution transmission electron microscopy, Mössbauer spectroscopy, magnetic measurements, and magnetooptical Faraday effect. It was shown that the ferrite particles vary highly in size, shape, stoichiometry, structural perfection, and space distribution depending on the preparation conditions. A correlation between the characteristics of nanostructured ferrite particles and magnetic properties of glasses has been established.

Аннотация: A coordinated investigation of the magnetic and electrical properties of polycrystalline cobalt oxide compounds CdCoO3, Gd0.9Ba0.1CoO3, and Gd0.9Sr0.1CoO3 is carried out. Undoped GdCoO3 reveals a low conductivity; a magnetic moment of 7.4 mu(B) per molecule, which is less than the theoretical value for the Gd3+ ion; and an asymptotic Curie temperature of -6 K. Doping GdCoO3 with barium and strontium to substitution of 10 at. % Gd brings about an increase in the conductivity and magnetic transitions at T = 300 K for Gd0.9Ba0.1CoO3 and T = 170 K for Gd0.9Sr0.1CoO3. The magnetization anomalies imply the formation of magnetic clusters. The behavior of the electrical conductivity at high temperatures suggests a variable activation energy. At low temperatures, Mott hopping conduction sets in.

Аннотация: The temperature and magnetic field dependences of the static magnetization of the polycrystalline rare-earth cobaltites GdCoO3 and SmCoO3 have been measured. It is shown that, below room temperature, the magnetization of both compounds derives primarily from the rare-earth ion paramagnetism. The GdCoO3 and SmCoO3 compounds have been found to differ substantially in magnetic behavior, which can be traced to differences in their electronic shell structures. The magnetic behavior of GdCoO3 is close to that of an array of free Gd3+ ions, whereas in SmCoO3 the deviation from the free-ion properties is very large because of the Sm3+ ground state being crystal-field split. Van Vleck magnetic susceptibility measurements of SmCoO3 suggest that the splitting is similar to 10 K.

Аннотация: The temperature dependence of the absorption spectra and magnetic circular dichroism due to f-f transitions from the H-6(15/2) to F-6 (5/2) and (6)(F (7/2) + H (5/2)) states in the Dy3+ ion in (Dy2O3-P2O5-SiO2-GeO2) and (Dy2O3-La2O3-Al2O3-B2O3-SiO2-GeO2) glasses and the temperature dependence of the Faraday effect were studied. The temperature dependence of the Faraday effect caused by f-d transitions was found to differ from that of the magnetic circular dichroism due to f-f transitions. It was shown that f-f transitions occur preferentially in Dy3+ ions associated into clusters. The origin of the paramagnetic magneto-optical activity of f-f transitions was analyzed. It was shown that the contributions to this activity can differ in value and sign and that the ratio between these contributions depends on the transition type. In some cases, this difference results in an anomalous temperature dependence of the magneto-optical activity.

Аннотация: B-11 nuclear magnetic resonance (NMR) spectroscopy was applied to study the crystalline, amorphous and crystallizing from an amorphous states of copper metaborate. The occurrence of trigonal BO3 units at the expense of converting tetragonal BO4 units was observed in amorphous CuB2O4. This fact explains the essential change of CuB2O4 magnetic properties under amorphization.

Аннотация: Magnetic susceptibility, EPR and optical properties 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; two magnetic transitions at 55 and 12 K have been detected and ascribed, respectively, to ferromagnetic and antiferromagnetic clusters of Gd3+ ions. The EPR spectra confirm the clustering at higher Gd contents. At low temperatures the cluster-related resonance indicates an onset of magnetic anisotropy. The clustering, depending on the Gd concentration, correlates with a shift to lower energies of the strong optical absorption band edge.
