ABSTRACT:
The present invention relates to a SQUID device for magnetic field measurement. The device is comprised of a body of superconducting material. First and second holes are located therein. A slot is provided joining the first and second holes. A contact unit is provided which is located in the slot thereby forming a weak link across the slot. The dimensions of the first and second holes produce first and second inductances respectively. These inductances have unequal magnitude.
