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…
Lattice-commensurate skyrmion texture in a centrosymmetric breathing kagome magnet
Max Hirschberger, Bertalan G. Szigeti, Mamoun Hemmida +15
Skyrmion lattices (SkL) in centrosymmetric materials typically have a magnetic period on the nanometer-scale, so that the coupling between magnetic superstructures and the underlyi…
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…
Non-destructive tomographic nanoscale imaging of ferroelectric domain walls
Jiali He, Manuel Zahn, Ivan N. Ushakov +8
Extraordinary physical properties arise at polar interfaces in oxide materials, including the emergence of two-dimensional electron gases, sheet-superconductivity, and multiferroic…
Magnetoelectric spectroscopy of spin excitations in LiCoPO4
Vilmos Kocsis, Sándor Bordács, Yusuke Tokunaga +7
We have studied spin excitations in a single-domain crystal of antiferromagnetic LiCoPO4 by THz absorption spectroscopy. By analyzing the selection rules and comparing the strength…
Spin excitations of magnetoelectric LiNiPO in multiple magnetic phases
Laur Peedu, Vilmos Kocsis, Dávid Szaller +11
Spin excitations of magnetoelectric LiNiPO are studied by infrared absorption spectroscopy in the THz spectral range as a function of magnetic field through various commensurat…
