Coherent phonon control beyond amplitude saturation in a sliding ferroelectric
Jan Gerrit Horstmann, Christoph Emeis, Andrin Caviezel +5
The breakdown of Hooke's law marks the onset of nonlinear behaviour: when displacements become large, restoring forces weaken and conventional proportionality fails. In quantum mat…
Emergent domain topology in the multiferroic hexagonal manganites
Aaron Merlin Müller, Lukas Heckendorn, Manfred Fiebig +1
Emergent topological phenomena in multiferroic materials arise from the intricate coupling between structural, electric, and magnetic order parameters. Hexagonal manganites provide…
Distribution of antiferromagnetic rare-earth domains in multiferroic DyTbFeO
Yannik Zemp, Ehsan Hassanpour, Jan Gerrit Horstmann +6
In many multiferroics, rare-earth and transition-metal orders exist side by side. For analyzing their interaction and its consequences for the multiferroic state, the associated do…
Effect of the depolarizing field on the domain structure of an improper ferroelectric
Aaron Merlin Müller, Amadé Bortis, Arkadiy Simonov +2
We show that, contrary to common belief, the depolarizing electric field generated by bound charges at thin-film surfaces can have a substantial impact on the domain structure of a…
