A method for growing a patterned superconductive oxide film of the general formula XZ2Cu3O6+x is disclosed, wherein X is yttrium, a lanthanide or a mixture thereof, Z is one or more alkaline earth elements and x is a number between 0 and 1. This patterned superconductive oxide film of XZ2Cu3O6+x is formed by preparing an aqueous solutuion of the nitrates of X, Z and Cu in the X:Z:Cu stoichiometric ratio of 1:2:3; spraying the aqueous nitrate solution onto a heated substrate to form on the substrate a thin film of XZ2Cu3Oy material, wherein y is an undefined number; spot-heating preselected portions of the thin film in an oxygen-rich atmosphere to convert the preselected portions into the patterned superconductive oxide film of XZ2Cu3O6+x; and removing the unheated thin film of XZ2Cu3Oy material with a solvent.
