Abstract:
We have fabricated and characterized a superconducting planar gradiometer
sensitive to the second-order spatial derivative of the magnetic field. Our device has been
patterned on a 12.8× 12.8 mm silicon chip on which the sensitive area of the gradiometer
and the SQUID inductance are generated by the same four 0.5-mm-square holes. We
measured the sensitivity both in flux-locked-loop (FLL) and in open-loop mode. With the
second method we used another dc-SQUID as amplifier and in this case we obtained the ...
