This patent describes an article capable of forming on heating a superconducting thin film having a superconducting transition temperature of greater than 30{degrees} K. It comprises: a substrate capable of withstanding temperatures requires to form the thin film and a mixed metal oxide layer capable of crystallizing to form the thin film on heating characterized in that a readily etchable, thin lift-off layer is interposed between the substrate and the mixed metal oxide layer and is selected from among copper, copper oxide and oxides and carbonates of alkaline earth metals which are components of the mixed metal oxide.
