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…
Reminiscence of a magnetization plateau in a magnetization processes of toy-model triangular and tetrahedral clusters
V. N. Glazkov
We discuss magnetization curves of a toy-model trigonal and tetrahedral clusters. Nonlinearity of magnetization with local minimum of differential susceptibility resembling known m…
Spin gap in a quasi-1D S=1/2 antiferromagnet K2CuSO4Cl2
T. A. Soldatov, A. I. Smirnov, K. Yu. Povarov +3
Electron spin resonance experiments in the quasi-1D S=1/2 antiferromagnet KCuSOCl reveal opening of a gap in absence of magnetic ordering, as well as an anisotropic shi…
Multiferroicity of CuCrO2 tested by ESR
S. K. Gotovko, T. A. Soldatov, L. E. Svistov +1
We have carried out the ESR study of the multiferroic triangular antiferromagnet CuCrO2 in the presence of an electric field. The shift of ESR spectra by the electric field was obs…
Exotic phases of frustrated antiferromagnet LiCu2O2
A. A. Bush, N. Büttgen, A. A. Gippius +6
7Li NMR spectra were measured in a magnetic field up to 17 T at temperatures 5-30 K on single crystalline LiCu2O2. Earlier reported anomalies on magnetization curves correspond to…
Search for a nematic phase in quasi-2D antiferromagnet CuCrO2 by NMR in electric field
Yu. A. Sakhratov, J. J. Kweon, E. S. Choi +3
The magnetic phase diagram of CuCrO2 was studied with a novel method of simultaneous Cu NMR and electric polarization techniques with the primary goal of demonstrating that regardl…
