## Abstract We have developed concentric multiloop DCβSQUID gradiometers for nondestructive evaluation, which were integrated on a 3 Γ 3 mm^2^ Si chip using Nb thinβfilm fabrication technology. In order to obtain high spatial resolution and to cancel magnetic noise, a coplanar concentric secondβord
