16 Jan 2007 | | Subject: | Superconductivity | | Abstract: | We present a study of the Nernst effect in amorphous superconducting thin films of Nb$_{0.15}$Si$_{0.85}$. The field dependence of the Nernst coefficient above T$_{c}$ displays two distinct regimes separated by a field scale set by the Ginzburg-Landau correlation length. A single function $F(xi)$, with the correlation length as its unique argument set either by the zero-field correlation length (in the low magnetic field limit) or by the magnetic length (in the opposite limit), describes the Nernst coefficient. We conclude that the Nernst signal observed on a wide temperature ($30 imes T_c$) and field ($4 imes B_{c2}$) range is exclusively generated by short-lived Cooper pairs. | | Source: | arXiv, cond-mat/0701376 | | Services: | Forum | Review | PDF | Favorites | |
