Abstract
Planar dc SQUID gradiometers with integrated antenna were designed for measurement of field distributions with gradients much smaller than 1 pT/cmHz(1/2) in an unshielded environment. Four types of first-order- gradiometer SQUIDs were fabricated in Pb-Pb technology and investigate d. Their layouts are highly symmetrical and they can be made also with HTS materials. Further reduction of the effect of disturbances was ac hieved with a second order gradiometer realized electronically. The st able function of the systems under unshielded conditions is shown.
