Thin films ofthe high Tc compound YBa2CusOj, with good electrical and structural properties have been prepared. Our method consists of d.c. sputtering by an YCu3 target and thermal Ba evaporation in 02-Ar atmosphere. The obtained films have transition onset at ~ 90Ä and TC(R=0)=70K. X-rays spectra show a preferential orientation of the c-axis perpendicular to the plane of the film. Measurements of critical current have been performed. A photolitographic technique has also been realized.

Abstract
Thin films ofthe high Tc compound YBa2CusOj, with good electrical and structural properties have been prepared. Our method consists of d.c. sputtering by an YCu3 target and thermal Ba evaporation in 02-Ar atmosphere. The obtained films have transition onset at ~ 90Ä and TC(R=0)=70K. X-rays spectra show a preferential orientation of the c-axis perpendicular to the plane of the film. Measurements of critical current have been performed. A photolitographic technique has also been realized.File in questo prodotto:
