Non-reciprocal neutral ferroelectric domain walls in BiFeO3
M. A. P. Goncalves, M. Graf, M. Pasciak +1
This paper analyzes a peculiar phenomenon of non-reciprocal domain wall pairs and illustrate the implications in ab-initio-based atomistic computational experiments with (112)-orie…
Pyramidal charged domain walls in ferroelectric BiFeO
Pavel Marton, Marek Paściak, 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…
BiFeO nanoparticles at low-temperature using atomistic simulations -- surface charge distribution and terminations
Mauro A. P. Goncalves, Monica Graf, Marek Pasciak +1
This paper analyzes how the ferroelectric properties of cubic-like BiFeO nanoparticles are affected by different terminations and charge distributions at the surface using ab-i…
Antiskyrmionic ferroelectric medium
Mauro A. P. Gonçalves, Marek Paściak, Jiří Hlinka
Typical magnetic skyrmion is a string of inverted magnetization within a ferromagnet, protected by a sleeve of a vortex-like spin texture, such that its cross-section carries a pos…
Zig-zag charged domain walls in ferroelectric PbTiO
Pavel Marton, Mauro A. P. Gonçalves, Marek Paściak +5
We report a theoretical investigation of a charged 180 domain wall in ferroelectric PbTiO, compensated by randomly distributed immobile charge defects. For this we util…
