The epitaxial growth of CeO{sub 2} on various (001) metal surfaces using pulsed-laser deposition is discussed. In particular, the growth of (001) CeO{sub 2} on (001) Pd, Ag, and Ni is described. Emphasis is given to the specific deposition conditions which successfully alleviate the formation of native oxides at the metal/metal oxide interface. The control of the epitaxial relationships between the oriented oxides films and the underlying noble and oxidizing metal surfaces is addressed. In addition, recent use of these heterostructures in the epitaxial growth of high temperature superconducting films on biaxially-textured metal substrates for superconducting wire development is described.
