Abstract
Pickup coils constructed by superconductors and a SQUID part are formed on a single substrate. The pickup coils are parallelly connected to two other superconductors (inductance of the SQUID ring) in a SQUID ring, which consists of two Josephson junctions and two superconductive lines. Each of the superconductors can be a superconductive line of one loop or a washer type coil. Each pickup coil occupies about one half of the area of the substrate and the SQUID and the pickup coils are symmetrical with respect to the center line of the substrate.
