摘要：
We show that in a certain range of parameters the interaction between vortices causes significant enhancement of galvanomagnetic effects in thin superconducting films, as opposed to thick films. In particular, the Nernst coefficient acquires a contribution exceeding the single-vortex term at relatively small external magnetic fields. The possibility of inducing the dc voltage due to either vortex-antivortex pair production by external ac currents or pair-breaking radiation is also discussed. Our results give a possible explanation for the experiments of A. Gerber and G. Deutcher.
