ABSTRACT
An integrated system of a thin-film niobium dc superconducting quantum interference device (SQUID) and a second order gradiometer on a planar substrate is described. The system consists of adc SQUID with eight loops in parallel, each sensitive to the second derivative ∂ ²B[sub z]/∂x² of the magnetic field. The calculated SQUID inductance is 1.3 nH. With an overall size of 16 × 16.5 mm² a sensitivity of 1.5 × 10[sup -9] Tm[sup -2] Hz[sup -1/2] is obtained. The measured transfer function for uniform fields perpendicular to the plane of the gradiometer is 2.1 × 10[sup -7] T φ[sup -1].
