Structure and magnetism of orthorhombic epitaxial FeMnAs
(American Chemical Society, 2013-08)
The molecular beam epitaxy growth of Fe on MnAs/GaAs(001) leads to the formation of an epitaxial FeMnAs phase at the Fe/MnAs interface. The investigation of the structure by high angle annular dark field imaging in a ...
Study of the hydrostatic pressure on orthorhombic IV–VI compounds including many-body effects
(Elsevier Science, 2011-05)
We performed a fully ab initio study of the relaxed volume optimization of the four orthorhombic IV–VI compounds (GeS, GeSe, a-SnS and SnSe), finding good agreement with experimental data from the literature. Based on the ...
Preparation of lanthanum doped Bi4Ti3O12 ceramics by the polymeric precursor method
Lanthanum-modified bismuth titanate, Bi4 - xLaxTi3O12 (BLT) ceramics, with x ranging from 0 to 0.75 were prepared by the polymeric precursor method. Orthorhombicity of the system is decreased with the increase of lanthanum ...
Synthesis of orthorhombic Sb2O3 branched rods by a vapor–solid approach
In this work, Sb2O3 nanorods, microrods and crystals were synthesized by a carbothermal reduction driven vapor–solid(VS) process. Aiming to provide data on the structure of these samples XRD, FEG-SEM and Raman spectroscopy ...
Optical phonon characteristics of an orthorhombic-transformed polymorph of CaTa2O6 single crystal fibre
(Institute of Physics - IOPBristol, 2014-03)
Infrared-reflectivity spectroscopy and micro-Raman scattering were used to determine the optical phonon features of orthorhombic calcium tantalite (CaTa2O6) single crystal fibres. The fibres, obtained by the Laser-Heated ...
Crystal structure of orthorhombic ferrous nitroprusside: Fe Fe CN 5NO .2H2O
(Powder Diffraction, 2013-01-16)
The structure of two orthorhombic nitroprussides:Cd[Fe(CN)5NO]·2H2O and Zn[Fe(CN)5NO]·2H2O
A theoretical investigation of the structural and eletronic properties of orthorhombic CaZrO3
A CaZrO3 (CZO) powder was prepared by the soft chemical, polymeric precursor method (PPM). The CZO crystalline structure was investigated by powder X-ray diffraction (XDR), Retvield Refinament data, Raman spectra and ...
Polaron liquid-gas crossover at the orthorhombic-rhombohedral transition of manganites
(AMER PHYSICAL SOC, 2008)
High-resolution synchrotron x-ray powder diffraction in La(0.7)Ca(0.3)MnO(3) shows in detail a first-order structural phase transition from orthorhombic (space-group Pnma) to rhombohedral (space-group R (3) over barc) ...
