Title: High performance YBCO films. Report for 25 February-25 May 1994

Abstract

A Bi2O3-based glass composition was found suitable for use under typical YBCO deposition conditions, which is in a vacuum under partial oxygen pressure at about 750 deg C. It was experimently determined that a Ag capping layer thickness of about 5 microns is needed for use with this glass. This Ag thickness will prevent any degradation in the silver layer's conducting properties due to Ag/glass interaction during the glass firing operation at 640 deg C. Lanthanum aluminate samples with YBCO topped with a thin layer of strontium titanate (STO) were prepared by Neocera and had excellent YBCO surface resistance properties as measured with a dielectric resonator test system. These samples will be used to test the compatibility of the YBCO with the silver capping layer deposited over the STO.
