Conductive articles made from mixed metal oxides, and processes for their preparation.

摘要

A patterned crystalline superconducting layer is formed by first providing a copper oxide lift-off layer (9) under an amorphous metal oxide superconducting precursor layer (17) and then photolithographically forming a pattern in the layers. The patterned layers are then heat treated to form the final crystalline superconducting layer.
