Resumen

Results on the temperature and magnetic field dependence of current-voltage characteristics (CVC) are presented for SNS-type 2D ordered array of Nb-Cu0.95Al0.05-Nb junctions. The critical current IC (T, H) and the power exponent a (T, H) = 1 + Φ0 IC (T, H) / 2 kB T of the nonlinear CVC law V = R [I - IC (T, H)]a (T, H) are found to have a maximum at non-zero value of applied magnetic field Hp = 225   Oe, which is attributed to manifestation of π-type Josephson contacts in our sample.
