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…
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…
Experimental realization of a 2D fractional quantum spin liquid
R. Coldea, D. A. Tennant, A. M. Tsvelik +1
The ground-state ordering and dynamics of the two-dimensional (2D) S=1/2 frustrated Heisenberg antiferromagnet Cs_2CuCl_4 is explored using neutron scattering in high magnetic fiel…
