| Outline of Final Research Achievements |
The atomic magnetometer was developed toward magnetoencephalography (MEG). The operation cost of the atomic magnetometer is lower than the SQUID which is used as the magnetometer for the MEG. The operation conditions of the atomic magnetometer, such as the laser light power and the width of the frequency modulation of the laser light, were optimized. The field sensitivity on the order of 10 pT/√Hz was achieved. We measured the please magnetic field whose magnitude was about 300 pT and confirmed the magnetometer operation. In this study, we laid the groundwork of the atomic magnetometer toward the magnetoencephalography.
