Title: Structure of rare-earth chalcogenide glasses by neutron and x-ray diffraction

Abstract

The method of neutron diffraction with isomorphic substitution was used to measure the structure of the rare-earth chalcogenide glasses (R ₂X ₃) _0.07(Ga ₂X ₃) _0.33(GeX ₂) _0.60 with R = La or Ce and X = S or Se. X-ray diffraction was also used to measure the structure of the sulphide glass. The results are consistent with networks that are built from GeX ₄ and GaX ₄ tetrahedra, and give R-S and R-Se coordination numbers of 8.0(2) and 8.5(4), respectively. The minimum nearest-neighbour R-R distance associated with rare-earth clustering is discussed.

Structural analysis of WO ₃ -TeO ₂ glasses by neutron, high energy X-ray diffraction, reverse Monte Carlo simulations and XANES

Journal Article Khanna, Atul ; Fábián, Margit ; Hirdesh, . ; ... - Journal of Non-Crystalline Solids

The structure of WO ₃-TeO ₂ glasses containing 15, 20 and 25 mol% WO ₃ are studied by neutron diffraction (ND), high energy X-ray diffraction (XRD) and X-ray Absorption Near Edge spectroscopy (XANES). The short-range structural properties of glasses i.e. Te-O and W-O speciation, coordination number distributions, bond-lengths, and the O-Te-O, O-W-O and O-O-O bond angle distributions in the glass network are determined by the Reverse Monte Carlo (RMC) simulations of the ND and XRD data. RMC technique successfully determined all partial pair correlation functions and the coordination number distributions revealed that glass network consists predominantly of TeO ₄ andmore »« less

Network vs Molecular Structural Characteristics of Ge-Doped Arsenic Sulfide Glasses: A Combined Neutron/X-ray Diffraction, Extended X-ray Absorption Fine Structure, and Raman Spectroscopic Study

Journal Article Soyer-Uzun, S. ; Sen, S ; Aitken, B - Journal of Physical Chemistry C

Combined neutron/X-ray diffraction, Ge and As K-edge extended X-ray absorption fine structure analysis, and Raman spectroscopy are employed to study the compositional dependence of the short- and intermediate-range structures of As-rich GexAsyS100-x-y glasses with a constant Ge:As atomic ratio of 1:17.3. The structures of glasses with compositions near stoichiometry (35 ? x + y ? 43) are dominated by the presence of a predominantly heteropolar-bonded As2S3 network. However, an increasing metal content (x + y = 55) results in a novel glass consisting predominantly of As4S3 molecules, held together by van der Waals forces. The formation of this 'molecular' glassmore »« less

Structure and magnetism of new rare-earth-free intermetallic compounds: Fe _3+xCo _3-xTi ₂ (0 ≤ x ≤ 3)

Journal Article Balasubramanian, Balamurugan ; Das, Bhaskar ; Nguyen, Manh Cuong ; ... - APL Materials

Here, we report the fabrication of a set of new rare-earth-free magnetic compounds, which form the Fe ₃Co ₃Ti ₂-type hexagonal structure with P-6m2 symmetry. Neutron powder diffraction shows a significant Fe/Co anti-site mixing in the Fe ₃Co ₃Ti ₂ structure, which has a strong effect on the magnetocrystalline anisotropy as revealed by first-principle calculations. Increasing substitution of Fe atoms for Co in the Fe ₃Co ₃Ti ₂ lattice leads to the formation of Fe ₄Co ₂Ti ₂, Fe ₅CoTi, and Fe ₆Ti ₂ with significantly improved permanent-magnet properties. A high magnetic anisotropy (13.0 Mergs/cm ³) and saturation magnetic polarizationmore »« less
