Integrated Thin Film DC Squids.
Abstract
A new thin film low temperature facility has been developed and used for work on three aspects of DC SQUIDS. First, ellipsometric studies have been made of the process of RF sputter-etch oxidation of Pb-In alloys and of Nb. Second, structures based on Nb-NbOx-Pb/In Josephson junctions have been produced and successfully operated as planar SQUIDs with a flux noise of 0.000085 Phi sub o sq rt Hz. Finally, all Nb structures, based on Nb-NbOx/Au-Nb junctions, have been operated as SQUIDs though so far with inferior noise performance (0.05 Phi sub o sq rt Hz). Work is proceeding on the production of integrated magneometric structures using photolithographic techniques to etch planar flux-transformers and the associated components. (Author)
