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…
Large ordered moment with strong easy-plane anisotropy and vortex-domain pattern in the kagome ferromagnet FeSn
Lilian Prodan, Donald M. Evans, Sinéad M. Griffin +8
We report the structural and magnetic properties of high-quality bulk single crystals of the kagome ferromagnet FeSn. The dependence of magnetisation on the magnitude and orien…
Strain driven conducting domain walls in a Mott insulator
L. Puntigam, M. Altthaler, S. Ghara +5
Rewritable nanoelectronics offers new perspectives and potential to both fundamental research and technological applications. Such interest has driven the research focus into condu…
Resolving structural changes and symmetry lowering in spinel FeCr2S4
Donald M. Evans, Ola G. Grendal, Lilian Prodan +7
The cubic spinel FeCr2S4 has been receiving immense research interest because of its emergent phases and the interplay of spin, orbital and lattice degrees of freedom. Despite the…
Contact-free reversible switching of improper ferroelectric domains by electron and ion irradiation
Erik D. Roede, Aleksander B. Mosberg, Donald M. Evans +4
Focused ion beam (FIB) and scanning electron microscopy (SEM) are used to reversibly switch improper ferroelectric domains in the hexagonal manganite ErMnO. Surface charging is…
Insulating improper ferroelectric domain walls as robust barrier layer capacitors
Lukas Puntigam, Jan Schultheiß, Ana Strinic +7
We report the dielectric properties of improper ferroelectric h-ErMnO. From the bulk characterisation we observe a temperature and frequency range with two distinct relaxation-…
