Micromagnetic calculation of magnetostatic oscillation modes of an orthogonally magnetized disk of yttrium iron garnet / B. A. Belyaev, A. V. Izotov // Phys. Solid State. - 2013. - Vol. 55, Is. 12. - P. 2491-2500, DOI 10.1134/S1063783413120068 . - ISSN 1063-7834
Аннотация: The absorption spectrum of a normally magnetized disk of yttrium iron garnet, which is associated with resonances of magnetostatic oscillation modes excited by a homogeneous high-frequency magnetic field, has been investigated using a numerical analysis of the micromagnetic model developed for ferromagnetic objects. The distribution of magnetization oscillation amplitudes over the disk surface area has been obtained for the first four modes. A good agreement between the results of the micromagnetic simulation and the data of analytical calculations for special cases has proved the reliability and efficiency of the proposed approach in numerical experiments on the study of the magnetization dynamics in objects with different geometries and shapes, including multilayer magnetic film structures.

Аннотация: Garnet crystals of the composition Gd3Ga5O12:Nd3+ (concentration series CNd = 1-10 at. %) were grown from flux. In terms of spectroscopy, these crystals, unlike those grown from melts, form a medium with a single activator center. For the first time, continuous-wave lasing was excited by diode pumping with the use of Gd3Ga5O12:Nd3+ crystals at the wavelengths ?3 = 1.3315 and ?4 = 1.3370 ?m of the 4F3/2 > 4I13/2 channel and also the simultaneous generation at two wavelengths, ?1 = 1.0621 and ?2 = 1.0600 ?m, of the 4F3/2 > 4I11/2 channel.

Аннотация: Cr3+-activated mullite-type Bi2Ga(4-x)AlxO9 (x = 0, 1, 2, 3, and 4) solid solutions were prepared by the solid state reaction, and their spectroscopic properties were investigated in conjunction with the structural evolution. Under excitation at 610 nm, Bi2[Ga(4-y)Aly]3.97O9:0.03Cr3+ (y = 0, 1, 2, 3, and 4) phosphors exhibited broad-band near-infrared (NIR) emission peaking at ?710 nm in the range 650?850 nm, and the optimum Cr3+ concentrations and concentration quenching mechanism were determined. Except for the interesting NIR emission, the body color changed from white (at x = 0) to green (at x = 0.08) for Bi2Ga4?xO9:xCr3+, and from light yellow (at x = 0) to deep brown (at x = 0.08) for Bi2Al4?xO9:xCr3+, respectively. Moreover, as a result of variable Al/Ga ratio, the observed body color for Bi2[Ga(4-y)Aly]3.97O9:0.03Cr3+ (y = 0, 1, 2, 3, and 4) varied from deep brown to green. The relationship between the observed colors and their diffuse reflectance spectra were also studied for the understanding of the different absorption bands. The results indicated that Cr3+-doped Bi2Ga(4-x)AlxO9 solid solutions appeared as the bifunctional materials with NIR phosphors and color-tunable pigments.

Кл.слова (ненормированные):
carbonate-silicate melt -- graphite -- CO2 fluid -- iron carbide -- garnet -- redox gradient -- high-pressure experiment
Аннотация: Experimental modeling of the processes of formation of ferric carbonate-silicate melts through the carbonate-oxide-metal interaction is performed in the (Mg,Ca)CO3-SiO2-Al2O3-Fe0 system at 6.3 and 7.5 GPa and within 1150-1650 °C, using a multianvil high-pressure apparatus of “split-sphere” type (BARS). Two parallel reactions run in the subsolidus region (1150-1450 °C): decarbonation, producing pyrope-almandine (Fe# = 0.40-0.75) and CO2 fluid, and redox interaction between carbonate and Fe0, resulting in the crystallization of iron carbide in assemblage with magnesiowustite (Fe# = 0.75-0.85). It is shown that the reduction of carbonate or CO2 fluid by iron carbide and parallel redox interaction of magnesiowustite with CO2 produce graphite in assemblage with Fe3 + -containing magnesiowustite. In the temperature range of 1450-1650 °C, generation of carbonate-silicate melts coexisting with pyrope-almandine, magnesiowustite, magnetite, ferrospinel, and graphite takes place. The composition of the produced melts is as follows: SiO2 - 10-15 wt.%, X(FeO + Fe2O3) = 36-43 wt.%, and Fe3+/XFe - 0.18-0.23. These Fe3 + -enriched carbonate-silicate melts/fluids are saturated with carbon and are the medium of graphite crystallization. Oxide and silicate phases (almandine, ferrospinel, and magnetite) coexisting with graphite are also characterized by high Fe3+/XFe values. It has been established that Fe3 + -enriched carbonate-silicate melts can result from the interaction of Fe0-containing rocks with carbonated rocks. In the reduced mantle (with the presence of iron carbides or oxides), melts of this composition can be the source of carbon and the medium of graphite crystallization at once. After separation and ascent, these ferric carbonate-silicate melts can favor oxidizing metasomatism in the lithospheric mantle.

Аннотация: Garnet-type compound Ca3Ga2Ge3O12 and Cr3+-doped or Cr3+/Bi3+ codped Ca3Ga2Ge3O12 phosphors were prepared by a solid-state reaction. The crystal structure of Ca3Ga2Ge3O12 host was studied by X-ray diffraction (XRD) analysis and further determined by the Rietveld refinement. Near-infrared (NIR) photoluminescence (PL) and long-lasting phosphorescence (LLP) emission can be observed from the Cr3+-doped Ca3Ga2Ge3O12 sample, and the enhanced NIR PL emission intensity and LLP decay time can be realized in Cr3+/Bi3+ codped samples. The optimum concentration of Cr3+ in Ca3Ga2Ge3O12 phosphor was about 6 mol%, and optimum Bi3+ concentration induced the energy-transfer (ET) process between Bi3+ and Cr3+ ions was about 30 mol%. Under different excitation wavelength from 280 to 453 nm, all the samples exhibit a broadband emission peaking at 739 nm and the intensity of NIR emission increases owing to the ET behavior from Bi3+ to Cr3+ ions. The critical ET distance has been calculated by the concentration-quenching method. The thermally stable luminescence properties were also studied and the introduction of Bi3+ can also improve the thermal stability of the NIR emission.

Аннотация: The Lu2.98Ce0.01Y0.01Al5O12 and Y2.99Ce0.01Al5O12 phosphors were synthesized by solid state reaction at temperature 1623 K and pressure 1.5 × 107 Pa in (95% N2 + 5% H2) atmosphere. Under the conditions, the compounds crystallize in the form of isolated euhedral partly faceted microcrystals ∼19 μm in size. The crystal structures of the Lu2.98Ce0.01Y0.01Al5O12 and Y2.99Ce0.01Al5O12 garnets have been obtained by Rietveld analysis. The photoluminescence (PL) and X-ray excited luminescence (XL) spectra obtained at room temperature indicate broad asymmetric bands with maxima near 519 and 540 nm for Y2.99Ce0.01Al5O12 and Lu2.98Ce0.01Y0.01Al5O12, respectively. The light source was fabricated using the powder Lu2.98Ce0.01Y0.01Al5O12 phosphor and commercial blue-emitting n-UV LED chips (λex = 450 nm). It is found that the CIE chromaticity coordinates are (x = 0.388, y = 0.563) with the warm white light emission correlated color temperature (CCT) of 6400 K and good luminous efficiency of 110 lm/W. © 2015 American Chemical Society.

Аннотация: New garnet phosphors, Lu3−xYxMgAl3SiO12:Ce3+ (x = 0–3), which can be efficiently excited by blue light and emit the yellow-orange light, were developed using the solid solution design strategy combining the chemical unit substitution and the cation substitution. Crystal structures of the four compounds were reported for the first time via the Rietveld refinement of their powder XRD patterns. All phosphors show the general cubic garnet structure with the space group Iad. The specific occupancy of Lu/Y, Al/Mg, Al/Si and O atoms in different positions was identified. The evolution of cell parameters and Y/Lu/Ce–O bond lengths were identified. Photoluminescence properties were evaluated on aspects of emission/excitation spectra, internal/external quantum efficiency and thermal emission stability. Under the 450 nm blue light excitation, the phosphors exhibit bright yellow color emission, peaking in the 575–597 nm spectral range. The internal and external quantum efficiency can reach 83% and 58%, respectively. The emission red-shift in response to the Y/Lu ratio variation was discussed in relation to the local structure evolution. The phosphors are relatively promising to act as wavelength converter of blue light in white light emitting diodes.

Аннотация: High-optical-quality single crystals of the TmAl3(BO3)(4) compound were synthesized from a solution in the melt. The absorption spectra in the sigma and pi polarizations for the H-3(6) - F-3(4), H-3(6) - H-3(5), H-3(6) - H-3(4), H-3(6) - F-3(3), H-3(6) - F-3(2), H-3(6) - (1)G(4), and H-3(6) - D-1(2) transitions in the Tm3+ ion were recorded at room temperature. The transition intensities were analyzed in the framework of the Judd-Ofelt theory generalized to the case of anisotropic crystals, and the following parameters of the theory were obtained: Omega(2) = 6.14 x 10(-20) cm(2), Omega(4) = 3.09 x 10(-20) cm(2), and Omega(6) = 2.04 x 10(-20) cm(2). The lifetimes and the branching ratios were determined for all possible transitions.

Аннотация: Europium gallium garnet (EuGG) single crystals were grown from fluxes with various contents. Optical absorption spectra of EuGG grown from a flux containing calcium show an additional band in the ultraviolet and blue regions of the spectra as compared to the case of a calcium-free flux. Mossbauer spectra of the samples grown from the fluxes with different additives show no signs of other valence states of the europium ions except for 3+. However, they indicate changes in the crystal field due to the entrance of additive ions. The nature of the additional absorption must be the same as that for calcium-doped gadolinium gallium garnet, i.e., anion vacancies. Mossbauer isotope shifts and quadrupole splitting for EuGG are determined. (C) 2008 American Institute of Physics.
