Neutron scattering from deconfined spinons in the 2D frustrated quantum magnet Cs2CuCl4

Abstract:

High-resolution inelastic neutron scattering is used to explore the magnetic excitations in Cs2CuCl4, a quasi-2D spin-5 frustrated Heisenberg antiferromagnet on an anisotropic triangular lattice. In the spin liquid phase above the 3D ordering transition a broad continuum of excited states is observed, characteristic of excitations of pairs of spin-1/2 spinons of a resonating-valence-bond state. In the ordered phase stabilized at low temperatures by the weak inter-layer couplings a sharp spin-wave mode emerges below the continuum lower boundary. © 2004 Published by Elsevier B.V.
