Atacamite CuCl(OH) in High Magnetic Fields: Quantum Criticality and Dimensional Reduction of a Sawtooth-Chain Compound
L. Heinze, T. Kotte, R. Rausch +13
We report an extensive high-field study of atacamite CuCl(OH), a material realization of quantum sawtooth chains with weak interchain couplings, in continuous and pulsed ma…
Ga substitution as an effective variation of Mn-Tb coupling in multiferroic TbMnO3
O. Prokhnenko, N. Aliouane, R. Feyerherm +5
Ga for Mn substitution in multiferroic TbMnO has been performed in order to study the influence of Mn-magnetic ordering on the Tb-magnetic sublattice. Complete characterizati…
Magnetic-field induced effects on the electric polarization in RMnO3 (R = Dy, Gd)
R. Feyerherm, E. Dudzik, A. U. B. Wolter +8
X-ray resonant magnetic scattering studies of rare earth magnetic ordering were performed on perovskite manganites RMnO3 (R = Dy, Gd) in an applied magnetic field. The data reveal…
Coupling of frustrated Ising spins to magnetic cycloid in multiferroic TbMnO3
O. Prokhnenko, R. Feyerherm, M. Mostovoy +5
We report on diffraction measurements on multiferroic TbMnO3 which demonstrate that the Tb- and Mn-magnetic orders are coupled below the ferroelectric transition TFE = 28 K. For T…
Determining ethylene group disorder levels in -(BEDT-TTF)Cu[N(CN)]Br
A. U. B. Wolter, R. Feyerherm, E. Dudzik +4
We present a detailed structural investigation of the organic superconductor -(BEDT-TTF)Cu[N(CN)]Br at temperatures from 9 to 300 K. Anomalies in the dependence…
High-field magnetization study of the S = 1/2 antiferromagnetic Heisenberg chain [PM Cu(NO)(HO)] with a field-induced gap
A. U. B. Wolter, H. Rakoto, M. Costes +8
We present a high-field magnetization study of the = 1/2 antiferromagnetic Heisenberg chain [PM Cu(NO)(HO)]. For this material, as result of the Dzyaloshins…
