ABSTRACT:
Articles are disclosed in which an electrically conductive layer on a substrate exhibits a superconducting transistion temperature in excess of 90.degree. K. Conductive layers are disclosed comprised of a crystalline heavy pnictide mixed alkaline earth copper oxide. Processes of preparing these articles are disclosed in which a mixed oxide precursor composition is coated and heated to its thermal decomposition temperature to create an amorphous mixed metal oxide layer. The amorphous layer is then heated to its crystallization temperature.
