Seebeck effect in the mixed state of epitaxial YBa2Cu3O7
Abstract
The temperature dependence of the Seebeck coefficient in the mixed state of a superconductor is closely related to the resistivity due to flux motion. This is a result of the counterflow of normal current and supercurrent in the presence of a temperature gradient, as discussed by Ginzburg. Measurements of the Seebeck coefficient performed with epitaxial c-axis-oriented YBa2Cu3O7 films show excellent agreement with the theory. © 1991 The American Physical Society.
