AB  - We have studied experimentally and theoretically the electronic structure and x-ray absorption spectrum at the R.E.L3 - edge and x-ray emission spectra of Ni and P in the R.E.2Ni12P5 compounds. Crystal structure of the ternary phosphate Ce2Ni12P5 has been refined using X-ray powder diffraction pattern of the single phase sample with the same nominal composition, and the isotopic structure as for earlier known La2Ni12P5-type has been proved: space group P21/m, formula units Z = 2, lattice parameters are a = 1.07809(2) nm, b = 0.36869(1) nm, c = 1.31490(3) nm, b = 107.776(4), residual R-values are RI = 0.0681, RP = 0.0442 , RwP = 0.0603. The theoretical calculations have been carried out by means of the ab initio fully-relativistic spinpolarized Dirac linear muffin-tin orbital method. The calculations show good agreement with the experimental measurements. R.E.LIII - absorption spectra in ternary R.E.2Ni12P5 compounds were obtained at 78K and 300K using a tube spectrometer equipped with an RKD-01 co-ordinate detector. The mixed valence state of Ce and Eu was obtained in the Ce2Ni12P5 and Eu2Ni12P5 compounds.

AB  - We have studied experimentally and theoretically the electronic structure and x-ray absorption spectrum at the Yb L3-edge and x-ray emission spectra of M and P at the K- and L2,3 -edges in the mixed valence compound YbM2P2 (with ThCr2Si2 type crystal structure), where M=Fe, Co, Ni. The theoretical calculations have been carried out by means of the ab initio fully-relativistic spin-polarized Dirac linear muffin-tin orbital method. The calculations show good agreement with the experimental measurements. The LSDA +U with Ueff > 8.8 eV produces two independent self-consistent solutions YbNi2P2 with divalent Yb2+ and trivalent Yb3+ ions. For the divalent Yb ion we found a non-magnetic solution with fourteen 4f electron bands completely occupied and situated far below the Fermi level. For trivalent Yb3+ solution thirteen 4f electron bands are situated well below the Fermi level. The hole 4f level for the Yb3+ solution the completely empty and situated sufficiently far from the Fermi level, therefore YbNi2P2 belong to the in homogeneously mixed-valence compounds. The calculated total magnetic moment for the Yb3+ solution moment is dominated by the 4f compounds, the spin Ms and orbital Ml moments are 0.365 μB, and 1.135 μB, respectively. The spin and orbital moments at the Ni and P sites are very small: Ms Ni= - 0.0028 B, MsP=-0.0017 μB, MlNi =-0.0019 μB and MlP =0.0004 μB. Both the trivalent and the divalent Yb ions in are reflected in the experimentally measured Yb L3 x-ray absorption spectrum simultaneously. We found that the best agreement between the experimental spectrum and sum of the theoretically calculated Yb2+ and Yb3+ spectra is achieved with 73% ytterbium ions 2+ state and 27% ions in 3+ state. We found that the effect of the electronic quadrupole E2 transitions as well as the core-hole effect in the final states has minor influence on the intensity and the shape of the Ni and P K and L2.3 emission spectra as well as on the Yb L3 absorption spectrum. We would like to point out that the LSDA +U method which combines LSDA with a basically static, i.e. Hartree-Fock-like, mean –field approximation for a multi-band Anderson lattice model does not contain true many body physics. However, this method can be considered as the first step towards a better description of strongly correlated electron systems. The LSDA +U method provides the correct energy position of 4f energy bands and gives a reasonable description of the XAS and XES properties in YbNi2P2. However, the energy band structure for finite temperatures and the presumed Kondo lattice and mixed valence behavior in YbNi2P2 clearly requires a treatment that goes beyond a static mean-field approximation and includes dynamical effects, e.g., the frequency dependence of the sell-energy.

AB  - The valence band electronic structure of compounds with the HfFe2S2 crystal lattice type has been established for the first time based on X-ray emission spectroscopy measurements. Band structure and theoretical spectra of X-ray emission bands of atoms located in non-equivalent crystallographic positions are calculated by means of the LMTO method. A satisfactory agreement between theoretical and experimental data is achieved. As it can be seen from the performed calculations and experimental data, the s-states of Si hybridize with the p-states Sc (Hf) and Fe and are located at the bottom of valence band. Contribution of the s-symmetry electrons to the chemical bond is substantially different for Si atoms located in non-equivalent crystallographic positions. 57Fe Mossbauer absorption measurements confirm iron atoms occupying non-equivalent positions in the crystal lattice.

AB  - High-energy spectroscopy has been used to study the electronic structure and valence state of new ternary intermetallic CeM2P2 (M=Fe, Co, Ni) compounds which crystallize in the ThCr2Si2 types. The calculations of electron energy bands E(k) and partial DOS for compounds were performed by the semi- relativistic linear muffin-tin orbital method without considerations of spin-orbit interactions. Effective filling numbers of electrons in different bands of components in CeM2P2 (M=Fe, Co, Ni) compounds have been calculated. Analysis of the results of calculations showed that the degree of occupation of spd-valence orbital of components varies and differs considerably from of external electrons in isolated atoms. The occupancy of d-orbital of M in the CeM2P2 compounds was shown to be significantly larger than in an isolated state. The electron configuration of P in compounds can be described as s1.4p2.8. LIII – absorption spectra Ce in the ternary CeM2P2 (M=Fe, Co, Ni) compounds were obtained at 78 K and 300 K using a tube spectrometer equipped with an RKD -01 coordinate detector. The mixed valence state of Ce was obtained in the investigated compounds. Surface morphologies CeM2P2 (M=Fe, Co, Ni) compounds are investigated by scanning tunneling microscopy (NT-MDT). The range scanning was 100 um x 100 um and 2 um x 2 um. The surface topography, distribution of grain diameter and area were obtained. The distribution of grain diameter and area of the CeM2P2 (M=Fe, Co, Ni) compounds is established. The picture of the distribution of the stiffness of the samples (amplitude and phase fluctuations) is obtained.

AB  - Rare-earth doped gadolinium gallium garnet (Gd3Ga5O12) has attracted much attention as important material for application in many optical devices. Recently, the nanostructure materials are considered as potentially useful for many technological applications. This paper presents the results of electron structure and spectral-luminescent properties of pure and Tb3+ doped Gd3Ga5O12 nanopowders prepared by a co-precipitation method. Analysis of diffractograms of the nanopowders showed that the minimum calcinations temperature that allowed getting a single garnet phase is T ~ 750oC. An average crystalline size of powders is about 35-47 nm. The surface microstructure was observed by using an atomic force microscope Solver P47H-PRO. The luminescence transition 5D4→7Fj (green emission) is dominated at the X-ray and photo excitation of nanosized Gd3Ga5O12 doped with Tb3+. The influence of the crystalline size and preparing condition on the luminescence properties of Gd3Ga5O12 is discussed. High-energy spectroscopy has been used to study the electron structure of the investigated rare-earth doped gadolinium gallium garnet (Gd3Ga5O12). The calculations of electron energy bands E(k) and partial DOS for compounds were performed by the semi relativistic linear muffin-tin orbital method without considerations of spin-orbit interactions. Effective filling numbers of electrons in different bands of components in garnet Gd3Ga5O12 been calculated. Between the experimental and calculated X-ray emission spectra garnet Gd3Ga5O12 good agreement has been obtained.

Recently, the nanostructure materials are considered as potentially useful for many technological applications. This paper presents the results of electron structure and spectral-luminescent properties of pure and Tb3+ doped Gd3Ga5O12 nanopowders prepared by a co-precipitation method. Analysis of diffractograms of the nanopowders showed that the minimum calcinations temperature that allowed getting a single garnet phase is T ~ 750oC. An average crystalline size of powders is about 35-47 nm. The surface microstructure was observed by using an atomic force microscope Solver P47H-PRO. The luminescence transition 5D4→7Fj (green emission) is dominated at the X-ray and photo excitation of nanosized Gd3Ga5O12 doped with Tb3+. The influence of the crystalline size and preparing condition on the luminescence properties of Gd3Ga5O12 is discussed. High-energy spectroscopy has been used to study the electron structure of the investigated rare-earth doped gadolinium gallium garnet (Gd3Ga5O12). The calculations of electron energy bands E(k) and partial DOS for compounds were performed by the semi relativistic linear muffin-tin orbital method without considerations of spin-orbit interactions. Effective filling numbers of electrons in different bands of components in garnet Gd3Ga5O12 been calculated. Between the experimental and calculated X-ray emission spectra garnet Gd3Ga5O12 good agreement has been obtained.",
