Abstract

The in-plane and out-of-plane thermal conductivities, κ_ab and κ_c, of a large single crystal of NdBa₂Cu₃O_7−x (NBCO) prepared by the top-seeded solution-growth method has been studied for the first time as functions of temperature and magnetic field up to high fields of 14 T. The κ_ab value of the annealed sample shows a rapid enhancement associated with the superconducting transition which is widely observed for high-T_c superconductors. The magnetic field dependence of κ_ab of a single crystal of NBCO has been examined with the field applied along the c-axis. It was found that at low fields, the κ_ab value of the NBCO compound first decreases rapidly and then gradually at high fields. Such nonlinear field dependence of κ_ab has been reported not only for RBa₂Cu₃O_7−x (R=rare-earth ion) but also Bi-2212 and Bi-2223 compounds.
