Fabrication and properties of high T /SUB c/ SNS microbridge series arrays

Conference · · IEEE Trans. Magn.; (United States)
OSTI ID:6486022
The fabrication and electrical characteristics of series connected arrays of high critical-temperature SNS Josephson microbridges are described, the initial purpose of the investigation being the development of voltage standards and ultrastable voltage references operational above 10K. Using Nb/sub 3/Sn/Cu step-edge microbridges, arrays containing 15 and 39 bridges have been fabricated which operate up to 16.5K. The arrays are irradiated by an antenna producing voltage steps in the array's I-V characteristics in which all the bridges are simulaneously locked to the first step.
