Abstract
A method of manufacturing a conducting or superconducting film comprises the steps of providing a powdered composition of complex oxide conducting or superconducting materials represented by the general formula: (La.sub.l-x M.sub.x).sub.y CuO.sub.4-.delta., where M is a member selected from the group of alkali earth metals and mixtures of the alkali earth metals: x=0 to 1. y=1.5 to 2.5, adding an organic solvent to the powdered composition to form a kneaded paste, printing the paste on a substrate before drying and firing.
