It has been reported recently that the diamagnetic response has been found in amorphous carbon films doped with copper, what have shown the superconducting state to be present in the films with a certain amount of copper at temperatures about 77 K. I

We describe the fabrication and characterization of superconductor/normal metal/superconductor (SNS) devices made with the high-temperature superconductor (HTS) YBa2Cu3O(7-x). Structures of YBa2Cu3O(7-x)/Au/Nb on c-axis-oriented YBa2Cu3O(7-x) were ma

TlCaBaCuO films using e-beam evaporation with subsequent sintering and annealing that have critical current densities of at least several hundred kA/sq cm, critical temperatures over 100 K, and surface resistance better than that of gold at 77 K and
