FIG. 1.

Flux-to-field conversion efficiency of an integrated dc SQUID magnetometer as a function of pickup coil side width for a perfect inductance match between the inductance of pickup coil and input coil.

Image of FIG. 2.
FIG. 2.

Miniaturized dc SQUID magnetometer. The sensor includes a superconducting flux transformer, an APF circuit, and a bipolar feedback coil for low cross-talk operations.

FIG. 3.

Voltage-flux characteristics of a miniaturized SQUID magnetometer with and without APF measured at . Comparing the voltage-flux transfer coefficients an APF gain is evaluated.

FIG. 4.

Device magnetic flux spectral density measured at in flux locked loop configuration, using a direct coupling scheme with a low noise readout electronics. Theoretical prediction for the white noise is indicated by the straight line.
