An enhancement of the in-plane thermal conductivity $\\kappa_{ab}$ is observed below T_c for all samples, with the greatest enhancement observed near optimal doping. The observed trends are consistent with the scattering of heat carriers by low-energy magnetic excitations. Upon entering the superconducting state, the formation of a spin-gap leads to reduced scattering and an enh","authors_text":"Andrew F. May, Athena S. Sefat, Brian C. Sales, Jonathan E.
