We report on experimental studies of critical current in Nb-Cu-Ni-Cu-Nb layered structures. Strong oscillations of the critical supercurrent were observed with the thickness variation of Ni. Using known microscopic parameters of Ni, we found reasonable agreement between the period of oscillations and the decay of the measured critical current, and theoretical calculations.
