The effect of Nb and O on the martensitic transformation in the Ti-Nb-O alloys
Kristián Šalata, Dalibor Preisler, Josef Stráský +3
This study examines the influence of niobium and oxygen on phase stability, crystal structure, and martensitic transformation pathways in Ti-Nb-O alloys. A series of Ti-(8-28)Nb-(0…
Quantitative Analysis of Light Induced Ion Segregation in Mixed-Halide Perovskites
Petr Machovec, Lukáš Horák, Milan Dopita +4
Mixed-halide perovskites (MHPs) offer good band gap tunability by stoichiometry changes, which is an essential property for the creation of multijunction solar cells. However, unde…
Simulation of ion demixing in halide perovskites using Cahn-Hilliard equation
V. Holý, M. Dopita, L. Horák +1
Light-induced ion demixing in mixed-halide perovskites is simulated numerically using the phenomenological Cahn-Hilliard equation. In the model we consider the energy of local elas…
The surface degradation and its impact on the magnetic properties of bulk VI_3
M. Kratochvílová, K. Uhlířová, M. Míšek +7
Despite belonging to a well-studied family of transition metal trihalides, VI_3 has received significant attention only recently. As a hard ferromagnetic van der Waals compound wit…
Disorder-induced time effect in the antiferromagnetic domain state of Fe1+yTe
Jan Fikáček, Jonas Warmuth, Fabian Arnold +8
We report on temperature-dependent soft X-ray absorption spectroscopy (XAS) measurements utilizing linearly polarized synchrotron radiation to probe magnetic phase transitions in i…
Crystal Structures and Phase Transitions of the van-der-Waals Ferromagnet VI3
Petr Doležal, Marie Kratochvílová, Václav Holý +8
The results of a single-crystal X-ray-diffraction study of the evolution of crystal structures of VI3 with temperature with emphasis on phase transitions are presented. Some relate…
Single crystal growth of TIMETAL LCB titanium alloy by a floating zone method
Jana Šmilauerová, Jiří Pospíšil, Petr Harcuba +2
The methodology of single crystal growth of metastable -Ti alloy TIMETAL LCB in an optical floating zone furnace is presented in this paper. Chemical compositions of both precur…
Ordered array of particles in -Ti matrix studied by small-angle X-ray scattering
Jana Šmilauerová, Petr Harcuba, Josef Stráský +7
Nanosized particles of phase in a -Ti alloy were investigated by small-angle X-ray scattering using synchrotron radiation. We demonstrated that the particles are spontaneous…
Strain-induced nonsymmorphic symmetry breaking and removal of Dirac semimetallic nodal line in an orthoperovskite iridate
Jian Liu, D. Kriegner, L. Horak +10
By using a combination of heteroepitaxial growth, structure refinement based on synchrotron x-ray diffraction and first-principles calculations, we show that the symmetry-protected…
Surface versus bulk contributions to the giant Rashba splitting in the ferroelectric α-GeTe(111) semiconductor
J. Krempaský, H. Volfová, S. Muff +14
In systems with broken inversion symmetry spin-orbit coupling (SOC) yields a Rashba-type spin splitting of electronic states, manifested in a k-dependent splitting of the bands. Wh…
