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…
Dynamic control of ferroic domain patterns by thermal quenching
Jan Gerrit Horstmann, Ehsan Hassanpour, Yannik Zemp +3
Controlling the domain structure of ferroic materials is key to manipulating their functionality. Typically, quasi-static electric, magnetic, or strain fields are exploited to tran…
Reversible long-range domain wall motion in an improper ferroelectric
M. Zahn, A. M. Müller, K. P. Kelley +8
Reversible ferroelectric domain wall movements beyond the 10 nm range associated with Rayleigh behavior are usually restricted to specific defect-engineered systems. Here, we demon…
