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…
Pyramidal charged domain walls in ferroelectric BiFeO
Pavel Marton, Marek PaÅciak, Mauro Gonçalves +4
Domain structures play a crucial role in the electric, mechanical and other properties of ferroelectric materials. In this study, we uncover the physical origins of the enigmatic z…
Paradoxical creation of a polydomain pattern by electric field in BaTiO3 crystal
Petr S. Bednyakov, Petr V. Yudin, Alexander K. Tagantsev +1
It is known that ferroelectric single crystals can be turned from a polydomain to a monodomain state by the application of an electric field. Here we report an unexpected opposite…
Thermal Stability and Topological Charge Fragmentation in Antiskyrmions of Rhombohedral Barium Titanate
Florian Mayer, JiÅÃ Hlinka
Antiskyrmions, as topological quasi-particles, hold significant promise for spintronics and nanoscale data storage applications. Using molecular dynamics simulations based on effec…
Orbital angular momentum impact on light scattering by phonons tested experimentally
A. Pylypets, F. Borodavka, I. Rafalovskyi +4
Polarized Raman spectra of piezoelectric bismuth germanate single crystal were recorded using vortex light in order to verify the predicted symmetry selection rules for Raman scatt…
