Bose-Einstein Condensation of Magnons in Cs2CuCl4
T. Radu, H. Wilhelm, V. Yushankhai +5
We report on results of specific heat measurements on single crystals of the frustrated quasi-2D spin-1/2 antiferromagnet Cs_2CuCl_4 (T_N=0.595 K) in external magnetic fields B<12…
Ground states of a frustrated spin-1/2 antifferomagnet: Cs_2CuCl_4 in a magnetic field
M. Y. Veillette, J. T. Chalker, R. Coldea
We present detailed calculations of the magnetic ground state properties of CsCuCl in an applied magnetic field, and compare our results with recent experiments. The materi…
Three-Dimensional Spin Fluctuations in Na0.75CoO2
L. M. Helme, A. T. Boothroyd, R. Coldea +4
We report polarized- and unpolarized-neutron scattering measurements of magnetic excitations in single-crystal Na0.75CoO2. The data confirm ferromagnetic correlations within the co…
Magnetic Studies of Polycrystalline and Single-Crystal NaxCoO2
D. Prabhakaran, A. T. Boothroyd, R. Coldea +2
We have investigated the preparation and bulk magnetic properties of NaxCoO2 in the range 0.5<x<0.95, including those for single crystals grown by the floating-zone method in an im…
Direct Measurement of the Spin Hamiltonian and Observation of Condensation of Magnons in the 2D Frustrated Quantum Magnet Cs2CuCl4
R. Coldea, D. A. Tennant, K. Habicht +3
We propose a method for measuring spin Hamiltonians and apply it to the spin-1/2 Heisenberg antiferromagnet Cs2CuCl4, which shows a 2D fractionalized RVB state at low fields. By ap…
Spin dynamics of the model 2D quantum antiferromagnet CFTD
H. M. Ronnow, D. F. McMorrow, R. Coldea +7
The magnetic excitation spectrum in the two-dimensional (2D) S=1/2 Heisenberg antiferromagnet copper deuteroformate tetradeuterate (CFTD) has been measured for temperatures up to T…
