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…
High-resolution neutron depolarization microscopy of the ferromagnetic transitions in NiAl and HgCrSe under pressure
Pau Jorba, Michael Schulz, Daniel S. Hussey +6
We performed neutron imaging of ferromagnetic transitions in NiAl and HgCrSe crystals. These neutron depolarization measurements revealed bulk magnetic inhomogeneities…
Magnetodielectric coupling in a Ru-based 6H-perovskite, Ba3NdRu2O9
Tathamay Basu, Alain Pautrat, Vincent Hardy +2
A large spin-orbit coupling is a way to control strong magnetodielectric (MD) coupling in a higher d-orbital materials. However reports are rare on such compounds due to often leak…
Importance of reorientational dynamics for the charge transport in ionic liquids
P. Sippel, S. Krohns, D. Reuter +2
Most ionic liquids contain at least one rather complex ion species exhibiting a dipolar moment. In the present work, we provide a thorough evaluation of broadband dielectric spectr…
Quantum Criticality of an Ising-like Spin-1/2 Antiferromagnetic Chain in Transverse Magnetic Field
Zhe Wang, T. Lorenz, D. I. Gorbunov +11
We report on magnetization, sound velocity, and magnetocaloric-effect measurements of the Ising-like spin-1/2 antiferromagnetic chain system BaCoVO as a function of tem…
Relaxation dynamics in the one-dimensional organic charge-transfer salt δ-(EDT-TTF-CONMe)Br
J. K. H. Fischer, P. Lunkenheimer, C. Leva +6
A detailed investigation of the charge-ordered charge-transfer salt δ-(EDT-TTF-CONMe)Br by thermal-expansion measurements and dielectric spectroscopy reveals three dyna…
Intrinsic charge dynamics in high-Tc AFeAs(O,F) superconductors
A. Charnukha, D. Pröpper, N. D. Zhigadlo +8
We report the first determination of the in-plane complex optical conductivity of 1111 high-Tc superconducting iron oxypnictide single crystals PrFeAsO0.6F0.35 and thin films SmFeA…
Sub-gap optical response across the structural phase transition in van der Waals layered α-RuCl
S. Reschke, F. Mayr, S. Widmann +7
We report magnetic, thermodynamic, thermal expansion, and on detailed optical experiments on the layered compound -RuCl focusing on the THz and sub-gap optical response acro…
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…
