Characteristics of HTS SQUID-based Susceptometer
Journal of Magnetics, Volume 3, Number 3, 30 Sep 1998, Pages 82-85
Abstract
A portable HTS RF SQUID-based system, weighing less than 20 kg has been built for susceptometry applications in weak magnetic fields, It includes a YBCO sensor for measuring the axial magnetic field component with a resolution of about 7×10-13 T/Hz1/2. This is determined by the intrinsic magnetic noise in the quasi-white noise region. There is a relaxation for a sudden increase in field due to magnetic flux creep in HTS. In this instance the time did not exceed 3~5 minutes.
