Pressure-induced symmetry lowering in Nb3Sn1-x superconductor
V. Svitlyk, M. Mezouar
Cubic Pm-3n Nb3Sn0.92 superconductor (Tc ~ 16 K) was found to exhibit tetragonal instabilities at the superconducting state (T = 10 K). These instabilities are manifested through t…
Pressure-induced enhancement of two-dimensionality in LaO1-xFxBi(Se/S)2 superconductors
V. Svitlyk, A. Krzton-Maziopa, M. Mezouar
Application of high pressure (HP) induces evolution from metallic to semi-metallic state in the layered superconducting LaO1-xFxBiSe2 phase, as concluded from ab initio calculation…
High-pressure polymorphism of BaFe2Se3
V. Svitlyk, G. Garbarino, A. D. Rosa +5
BaFe2Se3 is a potential superconductor material exhibiting transition at 11 K and ambient pressure. Here we extended the structural and performed electrical resistivity measurement…
Formation of single-phase disordered CsxFe2-ySe2 at high pressure
V. Svitlyk, E. Pomjakushina, A. Krzton-Maziopa +2
A single-phase high pressure (HP) modification of CsxFe2-ySe2 was synthesized at 11.8 GPa at ambient temperature. Structurally this polymorph is similar to the minor low pressure (…
Crystal Structure of BaFe2Se3 as a Function of Temperature and Pressure: Phase Transition Phenomena and High-Order Expansion of Landau Potential
V. Svitlyk, D. Chernyshov, E. Pomjakushina +5
BaFe2Se3 (Pnma, CsAg2I3-type structure), recently assumed to show superconductivity at ~ 11 K, exhibits a pressure-dependent structural transition to the CsCu2Cl3-type structure (C…
Synthesis, crystal and magnetic structure of iron selenide BaFe2Se3 with possible superconductivity at Tc=11K
A. Krzton-Maziopa, E. Pomjakushina, V. Pomjakushin +4
We report on synthesis of single crystals of BaFe2Se3 and study of their crystal and magnetic structures by means of synchrotron single crystal X-ray and neutron powder diffraction…
