Thermomagnetic Effect in YBa2Cu3Oy Single Crystals
Conference paper
Abstract
Various transport properties in the mixed state were investigated for YBa2Cu3Oy single crystals grown by a crystal-pulling technique. To discuss the vortex motion under a temperature gradient, we have measured the Nernst and the Seebeck effects together with resistivity and the Hall effect in various magnetic fields. For the observed temperature and magnetic field dependence of the Seebeck coefficient below Tc, we propose a new interpretation that the thermal angle θth is negligibly small and the quasiparticles are scattered by the vortex.
