The deposition of large area multilayers with smooth surfaces is an important topic for the realisation of high quality multiturn coils for flux transformers. We have developed a co-sputtering process from two metallic targets for the deposition of large areas of extremely smooth YBaCuO thin films. Conditions for epitaxial growth of MgO layers on YBaCuO have been investigated. Epitaxial multilayers with good electrical properties (Tc,o > 82 K) have been fabricated.
