SQUID systems, using either high temperature or low temperature superconductors, were developed for sensitive measurements in magnetically disturbed environments. They include the SQUIDs and fast SQUID electronics. Magnetometer SQUID systems are used for geophysical sounding, where they show superiority when compared to conventional induction coils for very deep sounding or fast measurement. Highly balanced 1 order gradiometer SQUID systems employed for the mapping of the earth’s magnetic field can resolve archaeological sites with extremely high quality. By using gradiometers of 2 order, even in normal laboratory environment, excellent human Magneto Cardiograms can be recorded.
