Abstract

In this study, we investigated highly sensitive measurement method to detect very weak magnetic signal during magnetic relaxation process from paramagnetic and diamagnetic materials. The noise caused by vibration of sample rotating component could be reduced by improving fixation mechanism of pick-up coil. Moreover, the change of rotation cycle which leads to waveform distortion by averaging the data was eliminated by maintaining constant rotation speed of sample. Using the improved system, the magnetic signal from pure water during magnetic relaxation could be detected and the waveform was the same as that without magnetic relaxation. Also, the decrease in magnetic signal intensity was observed with increasing the time after magnetization.
