Chirality-driven ferroelectricity in LiCuVO
Alexander Ruff, Peter Lunkenheimer, Hans-Albrecht Krug von Nidda +5
Chirality or the handedness of objects is of prime importance in life science, biology, chemistry and physics. It is also a major symmetry ingredient in frustrated magnets revealin…
Multiferroic spin-superfluid and spin-supersolid phases in MnCr2S4
Alexander Ruff, Zhaosheng Wang, Sergei Zherlitsyn +6
Spin supersolids and spin superfluids reveal complex canted spin structures with independent order of longitudinal and transverse spin components. This work addresses the question…
Frequency dependent polarisation switching in h-ErMnO
Alexander Ruff, Ziyu Li, Alois Loidl +8
We report an electric-field poling study of the geometric-driven improper ferroelectric h-ErMnO. From a detailed dielectric analysis we deduce the temperature and frequency dep…
Electronic bulk and domain wall properties in B-site doped hexagonal ErMnO
T. S. Holstad, D. M. Evans, A. Ruff +8
Acceptor and donor doping is a standard for tailoring semiconductors. More recently, doping was adapted to optimize the behavior at ferroelectric domain walls. In contrast to more…
Complex nature of magnetic field-induced ferroelectricity in GdCrTiO5
T. Basu, D. T. Adroja, F. Kolb +8
This work shows an unconventional route for spin-driven ferroelectricity originating from a metastable magnetic field-induced canting of chromium sublattice in the presence of gado…
Absence of polar order in LuFe2O4
A. Ruff, S. Krohns, F. Schrettle +3
LuFe2O4 often is considered as a prototypical multiferroic with polar order arising from the electronic degrees of freedom only ("electronic ferroelectricity"). In the present work…
