Abstract
A single layer YBaCuO-gradiometer galvanically coupled to DC-SQUIDs were prepared on bicrystal substrates. The devices were operated at 77 K without any shielding. The best performance obtained was a field gradient resolution of 0.5 pT/cm/spl radic/(Hz) for a device with a baseline of 7 mm and a pickup-area of 2 cm/sup 2/.<>
