摘要：

For practical purposes of SQUIDs, the magnetic field sensitivity should be enhanced. Since the flux capture area of SQUIDs is proportional to the product of the hole size and the outer dimension of the washer, higher magnetic field sensitivity is expected when the hole sizes or the washer sizes are enlarged. We have fabricated YBa2 Cu3O7-y SQUIDs with large washers (11 mm x 11 mm) and investigated these properties. As a result the magnetic field sensitivity was improved by a focussing effect and was 0.34 pT/Hz1/2 at a white noise level.
