| Outline of Final Research Achievements |
Optically pumped helium atomic magnetometers with atmospheric-pressure plasmas have been developed toward biomagnetic measurements. Conventional atomic magnetometers with alkali-metal atoms were examined for exploring the feasibility of biomagnetic measurements with the magnetometers. By solving the Bloch equation, we obtained the characteristics of the magnetometers and found that the lifetime of helium metastable atoms essentially influences the frequency characteristics. We developed the helium atomic magnetometer, which can measure the biomagnetic fields with post-processing such as signal averaging.
