摘要：

We report the use of a parallel magnetic field to suppress the superconducting gap and intergrain Josephson coupling in granular A1 films. The critical field H-c parallel to is spin paramagnetically limited, and the field induced superconductor-insulator (S-I) transition is found to go from second order to first order at 250 mK. In the vicinity of H-c parallel to, the field reproduces the quasireentrance and super-resistive behavior seen in the zero-field S-I transition. We show that the super-resistive phase is dominated by Coulomb blockade.
