Thermal transport and spin-phonon coupling in the one-dimensional antiferromagnetic spin chain compound CuSb$_2$O$_6$
ORAL
Abstract
We report thermal conductivity ($\kappa$) measurements on single crystals of the $S=1/2$ antiferromagnetic spin-chain compound CuSb$_2$O$_6$ over the temperature range $5{\rm K}\leq {\rm T}\leq 300 {\rm K}$. Similar measurements on the non-magnetic analog compound, ZnSb$_2$O$_6$, allow for a comparison of the lattice thermal conductivities. The role of spin-phonon coupling and twinning on the anisotropic thermal transport of CuSb$_2$O$_6$ will be discussed.
