Abstract

The Nernst effect has been observed in a high-temperature superconductor with a laser-pulse-heating method. Irradiating a Tl-Ba-Ca-Cu-O film by a short laser pulse, a voltage signal transverse to an external, surface-parallel magnetic field has been observed. This signal is attributed to vortex depinning and vortex transport driven by the laser-induced temperature gradient. We describe our ...
