Abstract

This paper reviews the theory and applications of SQUID magnetometers, in view of recent progress in SQUID technology and since the discovery of high-T_c superconductors (HTS). With their unrivalled sensitivity for magnetic flux and, consequently, for magnetic fields, voltages and currents, SQUID magnetometers have succeeded in a variety of applications, particularly in fields where a non-invasive, non-destructive type of detection and measurement is required. However, even with the introduction of HTS SQUID, the commercial impact of SQUID systems has been limited for a number of factors. We review these factors, and discuss few aspects that could contribute to the wider acceptance of SQUID applications.
