Abstract
A portable RF HTS SQUID-based susceptometer was used for small size magnetized sample testing in weak DC (up to 200 A/m) and AC (up to 4 A/m) magnetic fields. The system resolution for the magnetic moment is of the order of 1.6×10-10 A·m2. The measured DC susceptibility of a tested sample agrees well with the value obtained by using a commercial liquid helium susceptometer.
