High sensitivity quantum interference sensor has film ring enclosing inner region with at least one Josephson contact, film with holes with radius in range from 50 to 10000 nm

摘要

The HTSL sensor has a film (1) of HTSL material in the form of a ring enclosing an inner region (2) and contg. at least one Josephson contact (K1), whereby the film has a number of holes (L1-L6) with radius in the range from 50 to 10000 nm. The holes are specifically arranged near the Josephson contact or contacts.
