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…
Effect of pseudo-cubic (111)-oriented orthorhombic substrate facets on perovskite oxide thin film synthesis
K. Kjærnes, T. Bolstad, D. M. Evans +5
Strain engineering with different substrate facets is promising for tuning functional properties of thin film perovskite oxides. By choice of facet, different surface symmetries an…
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-…
Dimensionality-induced change in topological order in multiferroic oxide superlattices
Megan E. Holtz, Elliot S. Padgett, Rachel Steinhardt +5
We construct ferroelectric (LuFeO3)m/(LuFe2O4) superlattices with varying index m to study the effect of confinement on topological defects. We observe a thickness-dependent transi…
Local control of improper ferroelectric domains in YMnO
Lukas Kuerten, Stephan Krohns, Peggy Schoenherr +6
Improper ferroelectrics are described by two order parameters: a primary one, driving a transition to long-range distortive, magnetic or otherwise non-electric order, and the elect…
