Title: Investigation of transverse Peltier effect on top-seeded melt textureYBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}

Abstract

The transverse Peltier effect is investigated on the top-seeded melt texture superconductor YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} (YBCO). By restricting the heat absorbing or evolving on one of the sample{close_quote}s surfaces, the Peltier heat flow is converted into a temperature difference for measurement. The temperature difference is found proportional to the current applied, which is in accordance with the prediction of transverse Peltier effect. Based on a simplified model, the difference of the Seebeck coefficients between the {ital ab} plane and the {ital c} axis, {vert_bar}{ital S}{sub {ital ab}}{minus}{ital S}{sub {ital c}}{vert_bar}, is about 35 {mu}V/K. It is in good agreement with that of large single crystal [I. Terasaki, Y. Sato, S. Tajima, S. Miyamoto, and S. Tanaka, Physica C {bold 235-240}, 1413 (1994)]. The transverse Peltier effect is verified. This supports the idea that the off-diagonal thermoelectric effect is responsible for the anomalously high laser-induced transient transverse voltage on the oriented YBCO superconducting thin films. {copyright} {ital 1996 American Institute of Physics.}
