N2 - We report the experimental observation of a giant parametric amplification of a nonlinear response in single crystal Nb in the surface superconducting state. Measurements of the nonlinear susceptibility of Nb (Te ≈ 9.15 K), have been performed as a function of temperature, applied DC and AC fields in the presence of parametric AC pumping. Nonmonotonic changes of the nonlinear response have been found as a function of the DC, AC and pumping fields in a surface superconducting state of Nb.
