Universal behavior of spin-mediated energy transport in S = 1 / 2 chain cuprates : BaCu 2 Si 2 O 7 as an example


– Nonelectronic thermal conduction and heat-pulse propagation in solids; thermal waves. Abstract. – The thermal conductivity κ of the spin-1/2 chain cuprate BaCu2Si2O7 was measured along different crystallographic directions in the temperature region between 0.5 and 300 K. The thermal conductivity along the chain direction considerably exceeds that along… (More)
