Pulsed laser deposition of different CeO based buffer architectures have been performed onto biaxially textured Ni-based substrates.

Abstract
Pulsed laser deposition of different CeO based buffer architectures have been performed onto biaxially textured Ni-based substrates. The potential of both industrially available low-oxygen resistant magnetic. NiFe and NiCrW substrates have been explored. An attempt to reveal the influence CeO target doping and processing environment (vacuum or forming gas) on the formation of NiO as well as in-plane and out-of-plane orientation of the first buffer has been made. XRD has been used for layer texture characterisation. As-deposited YBCO layers were highly aligned on both types of substrate with out-of-plane and in-plane and scans having best FWHM values of 4 and 10 respectively. The quality of YBCO tapes as full- coated conductors or seeds for high-rate epitaxial growth by LPE is evaluated.
