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 ...
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 ...
Angular dependence of the magnetoelectric effect in orthorhombic HoMnO3 films
(American Physical Society, 2011-12)
Epitaxial orthorhombic HoMnO3 films were grown on Nb-doped SrTiO3 (001) single-crystal substrates. X-ray diffractometry showed a uniform crystallographic orientation with the c axis along the substrate normal and an ...
Synthesis of orthorhombic Sb2O3 branched rods by a vapor–solid approach
(2018-10-01)
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 ...
Correlated vortex pinning in slightly orthorhombic twinned Ba(Fe1−xCox)2As2 single crystals: Possible shift of the vortex-glass/liquid transition
(Amer Physical Soc, 2013-02)
The interest in twin-boundary (TB) planes as a source of vortex pinning has been recently renewed with the discovery of the new iron-arsenide pnictide superconductors. In the family of compounds Ba(Fe1−xCox )2As2 a structural ...
Preparation of lanthanum doped Bi4Ti3O12 ceramics by the polymeric precursor method
(2006-08-01)
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 ...
