Abstract
A system for magnetic characterization of soft magnetic materials in l ow field is described. Fields of 0.02 A/m can be applied and a good se nsibility is achieved by means of a Lock-In amplifier. Signals of 1 nV can be measured, and magnetic characterization with external stresses can be made. The measurements can be done from room temperature up to 973 K. The system allows to perform permeability, pinning field, Curi e temperature and disaccommodation measurements automatically.
