Abstract

Measuring the magnetic susceptibility of a material enable us to specify composition of the material. We have reported on development of a compact moving-sample magnetometer using high-temperature superconducting quantum interference device (HTS-SQUID). However, this magnetometer needs long time when we have to measure many samples. In order to solve this problem, we developed a compact magnetometer to analyze quantitative magnetic characteristics by our rapid measurement system using AC/DC functions. The optimal mounting position of pickup coils for the AC magnetic field measurement was optimized. The performance of the AC magnetic field measurement system was evaluated by measuring harmonic components of the AC magnetic response from a dispersion of iron oxide in styrene resin, when AC/DC magnetic field is applied. Using this system, the sample composition of ferromagnetic and diamagnetic substances can be evaluated from the mixed sample by measuring the harmonic components of the magnetic responses.
