Fabrication of High T(sub c) Superconductor Thin Film Devices: Center Director'sDiscretionary Fund

摘要

This report describes a technique for fabricating superconducting weak linkdevices with micron-sized geometries etched in laser ablated Y1Ba2Cu3O(x) (YBCO) thin films. Careful placement of the weak link over naturally occurring grain boundaries exhibited in some YBCO thin films produces Superconducting Quantum Interference Devices (SQUID's) operating at 77 K.
