From Spin Glass to Quantum Spin Liquid Ground States in Molybdate Pyrochlores
L. Clark, G. J. Nilsen, E. Kermarrec +5
We present new magnetic heat capacity and neutron scattering results for two magnetically frustrated molybdate pyrochlores: oxide LuMoO and oxyn…
Gapless spin liquid ground state in the S=1/2 vanadium oxyfluoride kagome antiferromagnet [NH4]2[C7H14N][V7O6F18]
L. Clark, J. C. Orain, F. Bert +10
The vanadium oxyfluoride [NH4]2[C7H14N][V7O6F18] (DQVOF) is a geometrically frustrated magnetic bilayer material. The structure consists of S=1/2 kagome planes of V4+ d1 ions with…
Field-Induced Freezing of a Quantum Spin Liquid on the Kagome Lattice
M. Jeong, F. Bert, P. Mendels +4
We report 17O NMR measurements in the S=1/2 Cu2+ kagome antiferromagnet Herbertsmithite ZnCu3(OH)6Cl2 down to 45mK in magnetic fields ranging from 2T to 12T. While Herbertsmithite…
Pair Correlations, Short Range Order and Dispersive Excitations in the Quasi-Kagome Quantum Magnet Volborthite
G. J. Nilsen, F. C. Coomer, M. A. de Vries +4
We present spatial and dynamic information on the s=1/2 distorted kagome antiferromagnet volborthite, Cu3V2O7(OD)2.2D2O, obtained by polarized and inelastic neutron scattering. The…
Determination of the single-ion anisotropy energy in a S = 5/2 kagome antiferromagnet using X-ray absorption spectroscopy
M. A. de Vries, T. K. Johal, A. Mirone +5
We report x-ray absorption and x-ray linear dichroism measurements at the Fe L2,3 edges of the geometrically frustrated systems of potassium and hydronium iron jarosite. Comparison…
Quantum magnetism in the paratacamite family: towards an ideal kagome lattice
P. Mendels, F. Bert, M. A. de Vries +7
We report MuSR measurements on the S=1/2 (Cu2+) paratacamite Zn_xCu_{4-x}(OH)_6Cl_2 family. Despite a Weiss temperature of -300 K, the x=1 compound is found to have no transition t…
