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…
Magnetodielectric coupling in a non-perovskite metal-organic framework
Tathamay Basu, A. Jesche, B. Bredenkotter +5
Multiferroicity and magnetodielectric coupling in metal-organic-frameworks (MOFs) is rare and so far restricted mainly to formate-based systems with perovskite structure. In the co…
Conductivity contrast and tunneling charge transport in the vortex-like ferroelectric domain patterns of multiferroic hexagonal YMnO3
E. Ruff, S. Krohns, M. Lilienblum +4
We deduce the intrinsic conductivity properties of the ferroelectric domain walls around the topologically protected domain vortex cores in multiferroic YMnO3. This is achieved by…
Impact of water on the charge transport of a glass-forming ionic liquid
P. Sippel, V. Dietrich, D. Reuter +4
Using dielectric spectroscopy and differential scanning calorimetry, we have performed a detailed investigation of the influence of water uptake on the translational and reorientat…
Ferroelectric properties of charge-ordered alpha-(BEDT-TTF)2I3
P. Lunkenheimer, B. Hartmann, M. Lang +4
A detailed investigation of the out-of-plane electrical properties of charge-ordered alpha-(BEDT-TTF)2I3 provides clear evidence for ferroelectricity. Similar to multiferroic alpha…
Dielectric signature of charge order in lanthanum nickelates
P. Sippel, S. Krohns, E. Thoms +7
Three charge-ordering lanthanum nickelates La2-xAxNiO4, substituted with specific amounts of A = Sr, Ca, and Ba to achieve commensurate charge order, are investigated using broadba…
