Nernst effect in high-T_c superconducting films

Abstract

We report measurements of the Nernst Effect in polycrystalline and epitaxial YBaCuO films. Such studies represent an important complement to Lorentz force experiments, since the thermal force is not subjected to spatial redistribution due to inhomogeneous flux pinning or damping. The Nernst effect also appears interesting for probing the superconducting fluctuation regime. © 1990, Elsevier Science Publishers B.V. (North-Holland). All rights reserved.
