Image of FIG. 1.
FIG. 1.

New feedback and pickup coil design. This configuration allows to maximize the flux-feedback current conversion factor.

Image of FIG. 2.
FIG. 2.

Numeric simulation of the magnetic field produced by the inducing SQUID having three different feedback coils as a function of the distance from the edge of the pickup coil. Note that the field produced by the bipolar coil is quite small in comparison with the square coils. In the inset, the curves relative to the distance of interest in logarithmic scale are reported.

FIG. 3.

(a) Picture of the fully integrated dc-SQUID magnetometer. (b) Detail view of the new feedback coil, the pickup loop, and the set of resistors for APF operation. (c) Magnified view of the feedback and pickup coil arrangement.

Image of FIG. 4.
FIG. 4.

The dc-SQUID magnetometer response in flux-locked-loop (FLL) mode, produced by three inducing SQUIDs having different feedback coils. The feedback signal corresponds to the saturation feedback current in the inducing SQUID. For the sake of clarity, the characteristics are vertically shifted. The cross talk ranges from 5% relative to small square coil (lower curve) to 0.7% for the bipolar feedback coil (upper curve).
