Abstract
We report an experimental study of the nonlinear response of single-crystal
Nb. In the stationary regime the non-linearity exists only in a surface su
perconducting state of Nb and it was found that the non-linear response is
non-monotonic function of the amplitude of excitation. The theoretical anal
ysis based on the two level model of a stochastic resonance (SR) phenomenon
provides a qualitative explanation of the experimental results.
