✦ Synopsis
A patterning process for YBCO films is described which does not change the critical properties of the superconducting films. Improvements achieved in the preparation and measuring technique described make it possible to perform reliable and reproducible measurements of critical current density of high To and high Jc film samples.

Obtaining repeatable critical current measurements for a high temperature superconductor (HTS) is a challenging task, since HTSs are highly susceptible to degradation due to mechanical stress, moisture, thermal cycling and aging. This paper discusses the development of a high temperature superconduc
