Abstract

The authors report on anisotropic thermal transport in the spin-1/2 triangular-lattice antiferromagnet Cs₂CuCl₄ close to the transition into the three-dimensional long-range-ordered state. This behavior is related to an additional heat-transport channel through magnetic excitations, that can best propagate along the direction of the largest exchange interaction.
