1. A method for forming a superconductive device operating at temperatures in excess of 40° K., including the steps of:
directing an energy beam onto selected regions of a layer of high Tc superconducting material, said energy beam producing sufficient damage in the irradiated portions of said layer of high Tc superconducting material to render said irradiated portions nonsuperconducting, the surface of said irradiated regions being
substantially coplanar with the remaining portions of said layer of high Tc superconducting material, and
continuing said irradiation at selected portions of said layer of high Tc superconducting material to form therein a continuous path exhibiting superconductivity at temperatures in excess of 40° K.,
the portions of said layer surrounding said continuous path of superconducting material being nonsuperconducting as a result
of said irradiation.
