Abstract

Superconducting film with a square lattice of artificial pinning centers (APC) was analyzed. It was found that at low dc currents, the differential resistance of the film showed the standard matching field anomaly. At higher dc currents, the differential resistance at each matching field was found to turn to a local maximum. The results show that this effect might indicate that the flux lines in the APC system change their flow mode as the dc current is increased.
