Measurements of the transverse ( kxy) and longitudinal ( kxx) thermal conductivity in high magnetic fields are used to separate the quasiparticle thermal conductivity ( kel xx) of the CuO2-planes from the phononic thermal conductivity in YBa 2Cu3O72d. kel xx is found to display a pronounced maximum below Tc. Our data analysis reveals distinct transport ( t) and Hall (tH ) relaxation times below Tc: Whereast is strongly enhanced, tH follows the same temperature dependence as above Tc.
