Abstract
Highly textured YBaCuO thin films were sputtered on MgO (100)-oriented single crystal substrates at ambient temperature followed by an anneal in oxygen for 1 h at temperatures up to 920 C. X-ray diffractograms of the highly textured films indicate an orientation of the c-axis of the YBaCuO lattice perpendicular to the substrate surface. There are strong indications that the oriented c-axis growth is due to a CuO self-flux effect. Auger measurements reveal a copper diffusion profile into the substrate down to a depth of more than 400 nm.
