Abstract:
A laminate of oxide superconductor thin films of single crystalline thin films comprising a single crystalline substrate, a c-axis oriented single crystalline thin film of an oxide superconductor having the formula YBa.sub.2 Cu.sub.3 O.sub.7-x (x is a number of from zero to 1) formed on said substrate, and an a-axis oriented single crystalline thin film of said oxide superconductor formed on said c-axis oriented single crystalline thin film, the c-axis oriented single crystalline thin film being a single crystalline thin film having a lattice constant of 11.60 angstroms.ltoreq.c.ltoreq.11.70 angstroms at a temperature of 20.degree. C. under an oxygen partial pressure of 160 Torr.
