Heat transport in quantum spin system Cu2Te2O5Cl2-xBrx

Insulating copper-tellurides (of the general formula Cu2Te205(Cl2_xBrx)) belong to the class of geometrically frustrated systems due to the tetrahedral arrangement of Cu2+ ions. Between 11.4 K and 18.2 K (depending on the Br content) coppertellurides exhibit a magnetic phase transition with the formation of the long-range spin-ordered state. We present the thermal conductivity data of copper-tellurides. For temperatures higher than the transition temperature, a resonant magneto-elastic coupling takes part in the phonon scattering. At the transition temperatures thermal conductivity increases for an order of magnitude, indicating that spin long-range ordered state switches off the phonon resonance scattering in the spin subsystem.
