Abstract
A magnetometer using a plurality of superconducting quantum interference devices (SQUIDs) includes a detecting part composed of a plurality of SQUIDs each detecting external magnetic flux, converting the detected external flux into a voltage value, and outputting a differential voltage of the converted voltage value, a signal-processing part for modulating, amplifying, and demodulating the differential voltage outputted by the detecting part, and a feedbacking part for converting a signal outputted by the signal-processing part into magnetic flux to feedback the signal to the loop of the SQUIDs.
