Paper Abstract

Superconducting Y1Ba2Cu3O7 thin films were prepared by in-situ oxygen plasma-assisted laser deposition. It was revealed that cw CO2 laser heating of substrate surface may be a method for reduction of particulate density. The buffer layers such as Ba(Sr)TiO3 and YSZ(111) were successfully experimented for preparation of good superconducting thin films. A multistep superfast CO2 laser annealing was investigated as a method of modification of the Y1Ba2Co3O7 thin films on Si. It is shown that N2 laser ablation may be a proper technique for patterning Y1Ba2Cu3O7 thin films. The films were characterized by EDAX, SEM, XRD and Raman spectroscopy.
