In addition to the obvious advantages of high sensitivity and fast response times of SQUID magne-tometers, the generation of a DC persistent current by the sample in such magnetometers permits a wide range of measurements to be made with them that are not possible with conventional spinner and vibration magnetometers. Examples of such measurements are described in this paper, including the measurement of the NRM of long cores, the determination of stress and thermal effects on magnetization.

SQUID Applications to Geophysics
“The SQUID, or Superconducting Quantum Interference Device, is an extremely sensitive magnetic field sensor based on the Josephson junction, with a basic sensitivity some 10,000 times greater than that of the best conventional magnetometers. This book is a collection of papers presented at the Workshop on SQUID Applications to Geophysics held at Los Alamos Scientific Laboratory in 1980.”
