Abstract
Results are presented from an experimental study of the crystallographic parameters of (1102)Al2O3/(001)CeO2/(001)YBa2Cu3O7−x film heterostructures fabricated by cathode sputtering at high substrate temperatures T=600–800°C. It is shown that the main limitation on the temperature for deposition of a YBa2Cu3O7−x film on a CeO2 surface is due to the chemical interaction between YBa2Cu3O7−x and CeO2 to form a polycrystalline BaCeO3 layer.
