    Abstract: YO987-028 DEVICES USING HIGH Tc SUPERCONDUCTORS AND METHOD FOR MAKING THE SAME A superconducting device operable at temperatures in excess of 30.degree.K and a method for making the device are described. A representative device is an essentially coplanar SQUID device formed in a single layer of high Tc superconducting material, the SQUID device being operable at temperatures in excess of 60.degree.K. High energy beams, for example ion beams, are used to convert selected portions of the high Tc superconductor to nonsuperconducting properties so that the material now has both superconducting regions and nonsuperconducting regions. In this manner a superconducting loop having superconducting weak links can be formed to comprise the SQUID device.
