PURPOSE:To decrease variation of the measured value by trembling of a magnetometer etc., by flowing a low frequency electric current on a RF coil and impressing an alternating magnetic field to an absorption cell. CONSTITUTION:Alternating voltage generated from a low frequency oscillator 11 is flowed to a RF coil 10 as an alternating electric current through a current regulator 12 and an alternating magnetic field Hh in a rectangular direction to an optical axis L is impressed to an absorption cell 4. The variation of the measured value accompanied by the position variation of a photomagnetic resonance magnetometer is negated by adjusting the intensity of the magnetic field Hh. |
