Outline of Final Research Achievements |
The high-sensitive magnetometer was developed for search of electric dipole moment which indicates direct evidence of time revearsal symmetry. Rubidium atoms were confined in a glass cell whose inner surface was coated with paraffin. The cell was irradiated by a single frequency laser beam and the rotation of beam polarization after passing the cell was analyzed to probe the magnetic field. The magnetic sensitivity of μG/√Hz was achieved, and the shot-noise limit of 30 pG/√Hz was evaluated. This paved the way for introducing this type of magnetometry in EDM experiments.
