Original Paper


The angle dependence at different temperatures of the longitudinal thermal conductivity \(\kappa_{xx}(\theta)\) in the presence of a planar magnetic field is presented. In order to study the influence of the gap symmetry on the thermal transport, angular scans were measured up to a few Kelvin below the critical temperature Tc. We found that the four-fold oscillation of \(\kappa_{xx}(\theta)\) vanishes at T > 20K and transforms into a one-fold oscillation with maximum conductivity for a field of 8 T applied parallel to the heat current. Nevertheless, the results indicate that the d-wave pairing symmetry remains the main pairing symmetry of the order parameter up to Tc. Numerical results of the thermal conductivity using an Andreev reflection model for the scattering of quasiparticles by supercurrents under the assumption of d-wave symmetry provide a semiquantitative description of the overall results.
