Abstract

The dissipation behavior in the mixed state of a high-Tc oxide superconductor YBa2Cu3O7-δ has been investigated by measuring thermomagnetic effects, namely the Ettingshausen and Nernst effects. These two effects were measured for the same sample prepared by the quench and melt growth (QMG) method without Pt addition. The Ettingshausen effect was also measured for a sample with 0.5% Pt. The temperature and magnetic field dependences of the temperature gradient produced by the Ettingshausen effect and the electric field induced by the Nernst effect are presented. Combining these data with the electrical resistivity and the thermal conductivity, the transport energy of a vortex line is obtained. The effect of the Pt addition on the Ettingshausen effect is also discussed.
