Abstract
A thin film SQUID device in which one or two thin film Josephson junctions are positioned at the hub of a wheel-shaped conductive structure including an outer closed loop rim and a plurality of radial arms or spokes formed on a substrate. A first group of alternate arms connects to one side of the junctions and a second group of intermediate arms connects to the other side of the junctions, the two groups of arms being insulated from each other at the hub. An overlying conductive pattern forms a coil in which the conductive turns of the coil include portions extending parallel to each of the arms to provide inductive coupling to currents circulating through loops formed by the groups of radial arms and rim.
