Observation of chiral solitons in the quantum spin liquid phase of LiCuVO
Christoph P. Grams, Daniel Brüning, Severin Kopatz +4
Quantum spin liquids represent a magnetic ground state arising in the presence of strong quantum fluctuations that preclude ordering down to zero temperature and leave clear finger…
Critical size limits for collinear and spin spiral magnetism in CoCrO
Dominika Zákutná, Adam Alemayehu, Jan Vlček +5
The multiferroic behavior of CoCrO results from the appearance of conical spin-spiral magnetic ordering, which induces electric polarization. The magnetic ground state has…
Ferroelectric order versus metallicity in SrCaTiO ()
Johannes Engelmayer, Xiao Lin, Fulya Koç +4
We report on a thermal-expansion study of the ferroelectric phase transition in insulating SrCaTiO () and its evolution upon increasing charge-carrier conc…
Large positive magneto-conductivity at microwave frequencies in the compensated topological insulator BiSbTeSe2
Mahasweta Bagchi, Lea Pitz-Paal, Christoph P. Grams +6
The bulk electronic properties of compensated topological insulators are strongly affected by the self-organized formation of charge puddles at low temperature, but their response…
Domain dynamics in LiCuVO: Evidence for polarized nanoregions
Christoph P. Grams, Severin Kopatz, Daniel Brüning +5
LiCuVO is a model system of a 1D spin-1/2 chain that enters a planar spin-spiral ground state below its Néel temperature of 2.4 K due to competing nearest and next nearest neig…
Charge transport in oxygen-deficient EuTiO: the emerging picture of dilute metallicity in quantum-paraelectric perovskite oxides
Johannes Engelmayer, Xiao Lin, Christoph P. Grams +5
We report on a study of charge transport in EuTiO single crystals with carrier density tuned across several orders of magnitude. Comparing this system with other quasi-cubi…
