Standard Measurement Method for Magnetic Properties of Fe-Based Amorphous Magnetic Materials

To establish the standard measurement method of magnetic properties of Fe-based amorphous magnetic materials, this paper investigates a single sheet tester (SST) for Fe-based amorphous magnetic materials. The influences of the material and structure of the yoke on the measurement results of magnetic properties of amorphous materials are revealed. The difference in the measurement method of magnetic field strength is also discussed from the standpoints of accuracy and repeatability. Furthermore, the difference in magnetic properties measured by a SST and a toroidal core is compared.
