摘要: A magnetometer for measuring a magnetic flux comprises plurality of superconducting quantum devices (SQUIDs) connected in series, each SQUID including: loop containing two Josephson junctions J1, J2 to other parallel; and flux-focussing region 116A, 116B, the configured generate screening current response flux, modulating corresponding voltage which is in-phase with array. The focussing may be an additional portion material integrally formed SQUID. Each focusing at least SQUIDs array from bicrystal high temperature superconductor. manufactured by depositing epitaxially layers superconductive conductive onto substrate, patterning using optical lithography etching argon ion beam.
