Soft Contrastive Learning for Unsupervised Discovery of Phases of Matter
Vít Beneš, Pavel Baláž, Dmytro Bohdanov +1
A machine learning (ML) framework for phase-diagram construction in condensed matter systems with unknown phase structure is presented. The method combines physically motivated des…
Unusual phase coexistence regime across the ferroelectric - paraelectric transition
M. Kopecký, J. Kub, E. de Prado +1
A PbTiO3 epitaxial thin film grown on a DyScO3 substrate was studied by x-ray diffraction in the temperature range of 20-500 degrees Celsius. It is found that the ferroelectric to…
Experimentally constrained modeling of the Pockels response of KNbO3 and KTaNbO3
Virginie de Mestral, Lorenzo Bastonero, Petr Bednyakov +6
The soft-mode of electro-optic (EO) metal-oxide perovskites plays a critical role in determining their Pockels responses. This is the case of potassium tantalate niobate (KTN), whi…
Giant dielectric permittivity in Nb-doped rutile crystals
D. Nuzhnyy, V. Bovtun, J. Petzelt +13
Dielectric properties of Nb-doped (~1.5 at%) rutile single crystals were studied in the 10-300 K temperature range (at frequencies below the MHz range down to 0.3 K) in a broad fre…
Photovoltaic creation of charged domain walls in barium titanate
P. S. Bednyakov, P. V. Yudin, A. K. Tagantsev +1
The optical control of domain structures in ferroelectrics is of great interest. In the present work, we demonstrate the reliable creation of charged domain walls - conductive chan…
Microscopic flexoelectricity in the canonical PMN relaxor
J. Hlinka
Previously reported neutron scattering investigations of the canonical relaxor ferroelectric perovskite oxide with a chemical formula Pb(Mg(1/3)Nb(2/3))O3 (PMN) are revisited in or…
