Epitaxial CeO2 buffer layers and YBa2Cu307\_~ thin films have been grown in situ on (1].02) sapphire by electron beam evaporation. Buffer layers of only 20 nm thickness inhibit interdiffusion between YBa2 Cu3 O7-6 and A12 03 as determined by depth profiling using x-ray photoelectron spectroscopy. Th
