NMR and NQR study of the tetrahedral frustrated quantum spin system Cu2Te2O5Br2 in its paramagnetic phase
Arnaud Comment, Hadrien Mayaffre, Vesna Mitrovic +4
The quantum antiferromagnet Cu2Te2O5Br2 was investigated by NMR and NQR. The 125Te NMR investigation showed that there is a magnetic transition around 10.5K at 9T, in agreement wit…
Ground state of the Kagome-like S=1/2 antiferromagnet, Volborthite Cu3V2O7(OH)2.2H2O
F. Bert, D. Bono, P. Mendels +4
Volborthite compound is one of the very few realizations of S=1/2 quantum spins on a highly frustrated kagome-like lattice. Low-T SQUID measurements reveal a broad magnetic transit…
Unusual magnetic properties of the low-dimensional quantum magnet Na2V3O7
J. L. Gavilano, E. Felder, D. Rau +5
We report the results of low-temperature measurements of the specific heat Cp(T), ac susceptibility chi(T) and 23Na nuclear magnetic resonance NMR of Na2V3O7. At liquid He temperat…
Anisotropic field dependence of the magnetic transition in Cu2Te2O5Br2
A. V. Sologubenko, R. Dell'Amore, H. R. Ott +1
We present the results of measurements of the thermal conductivity of Cu2Te2O5Br2, a compound where tetrahedra of Cu^{2+} ions carrying S=1/2 spins form chains along the c-axis of…
Longitudinal magnon in the tetrahedral spin system Cu2Te2O5Br2 near quantum criticality
C. Gros, P. Lemmens, M. Vojta +8
We present a comprehensive study of the coupled tetrahedra-compound Cu2Te2O5Br2 by theory and experiments in external magnetic fields. We report the observation of a longitudinal m…
A low-dimensional spin S = 1/2 system at the quantum critical limit: Na2V2O7
J. L. Gavilano, D. Rau, S. Mushkolaj +3
We report the results of measurements of the dc-susceptibility and the 23Na-NMR response of Na2V2O7, a recently synthesized, non metallic low dimensional spin system. Our results i…
