Conductivity Contrast and Tunneling Charge Transport in the Vortexlike Ferroelectric Domain Patterns of Multiferroic Hexagonal YMnO3
Ruff, E.; Krohns, S.; Lilienblum, M.; Meier, Dennis Gerhard; Fiebig, Manfred; Lunkenheimer, Peter; Loidl, Alois (Journal article, 2017)We deduce the intrinsic conductivity properties of the ferroelectric domain walls around the topologically protected domain vortex cores in multiferroic YMnO3. This is achieved by performing a careful equivalent-circuit ... -
Magnetoelectric coupling at the domain level in polycrystalline hexagonal ErMnO<inf>3</inf>
Schultheiss, Jan Erich; Puntigam, L.; Winkler, M.; Krohns, S.; Meier, Dennis; Das, H.; Evans, Donald Malcolm; Kézsmárki, I. (Journal article; Peer reviewed, 2024)We explore the impact of a magnetic field on the ferroelectric domain pattern in polycrystalline hexagonal ErMnO3 at cryogenic temperatures. Utilizing piezoelectric force microscopy measurements at 1.65 K, we observe ...
