A length scale for the superconducting Nernst signal above T${}_c$ in Nb${}_{0.15}$Si${}_{0.85}$

A. Pourret, H. Aubin, J. Lesueur +4

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…
