Ongoing advances in scanning probe microscopy techniques are continually expanding the possibilities for nanoscale characterization and correlated studies of functional materials.…
Domain-wall driven suppression of thermal conductivity in a ferroelectric polycrystal
Rachid Belrhiti-Nejjar, Manuel Zahn, Patrice Limelette +8
A common strategy for reducing thermal conductivity of polycrystalline systems is to increase the number of grain boundaries. Indeed, grain boundaries enhance the probability of ph…
Ferroelectric domain walls for environmental sensors
L. Richarz, I. C. Skogvoll, E. Y. Tokle +9
Domain walls in ferroelectric oxides provide fertile ground for the development of next-generation nanotechnology. Examples include domain-wall-based memory, memristors, and diodes…
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…
Relation between rare-earth magnetism and the magnetocaloric effect in multiferroic hexagonal manganites
R. Dragland, C. Salazar Mejía, I. Hansen +6
The magnetocaloric effect enables magnetic refrigeration and plays an important role for cooling at cryogenic temperatures, which is essential for emergent technologies such as hyd…
Magnetoelectric coupling at the domain level in polycrystalline ErMnO3
J. Schultheiß, L. Puntigam, M. Winkler +5
We explore the impact of a magnetic field on the ferroelectric domain pattern in polycrystalline hexagonal ErMnO3 at cryogenic temperatures. Utilizing piezoelectric force microscop…
Post-synthesis tuning of dielectric constant via ferroelectric domain wall engineering
L. Zhou, L. Puntigam, P. Lunkenheimer +7
A promising mechanism for achieving colossal dielectric constants is to use insulating internal barrier layers, which typically form during synthesis and then remain in the materia…
Coexistence of multi-scale domains in ferroelectric polycrystals with non-uniform grain-size distributions
K. Wolk, R. S. Dragland, E. Chavez Panduro +7
Engineering of ferroelectric domain structures enables direct control over the switching dynamics and is crucial for tuning the functional properties of ferroelectrics for various…
