Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we investigated the highly sensitive measurement method of a rotating sample magnetometer using HTS-SQUID for detecting a weak magnetic signal from paramagnetic and diamagnetic material. To improve the signal to noise (S/N) ratio of the developed system, the measured data was averaged and a digital low-pass filter was used to eliminate the various noises. Moreover, permanent magnet was used to magnetize the sample leading to the increase and the reduction of noise in the applied magnetic field. Consequently, the S/N ratio increased by optimizing various conditions and the sensitivity of the improved system was 1.4 × 10-9 emu.
