Abstrakt: We have designed and tested a set of YBa2Cu3O7-δ (YBCO) directly coupled superconducting quantum interference devices (SQUIDs). The proposed layout introduces a reduction of the device effective area that leads to high design flexibility for micromagnetometer sensors. SQUID magnetometers have been realized using YBCO grain boundary junctions fabricated on symmetric 30° [001] bicrystal substrates. Sensors have been characterized in a highly shielded environment confirming theoretical predictions. [ABSTRACT FROM AUTHOR]
