Abstract
Measurement of the mixed state thermoelectric power of pure and vanadium substituted 2223 pellets of the type (Bi0.6Pb0.2−y V y )2Sr2Ca2Cu3O x are presented for temperatures between 77 and 120 K. Mixed state Seebeck voltages for both pure and vanadium substituted samples show almost similar features. Our data forT>0.8T c could be explained, attributing the observed dissipation to the normal quasiparticle excitations. For temperatures below 0.8T c , we argue that the dominant contribution to the mixed state Seebeck voltage may originate from the dissipation induced by the fluctuations of the order parameter across the internal weak links.
