N2 - Giant enhancement of the nonlinear response of a single-crystal Nb sample, placed in a pumping ac magnetic field, has been observed experimentally. The experimentally observed amplitude of the output signal is about three orders of magnitude higher than that seen without parametric pumping. The theoretical analysis based on the extended double-well potential model provides a qualitative explanation of the experimental results as well as new predictions of two bifurcations for specific values of the pumping signal.
