Abstract
Measurement of magnetic fields by monitoring the Larmor precession of atomic spins is commonly used nowadays because of the high sensitivity and absolute measurement. This paper proposes a novel atomic magnetometer based on the self-sustaining method for large and fluctuating magnetic fields. In combination with the indefinitely persist Larmor precession signal, the sensitivity of the magnetometer increases following a much faster τ-1 rule beyond the atomic coherence lifetime. The maximum magnetic field have been experimentally demonstrated up to 40000 nT, the sensitivity achieved is 20 pT/√Hz and the frequency response bandwidth is 5 kHz, respectively. This magnetic field sensor is advantageous for applications requiring high sensitivity over a wide dynamic range such as geology and space physics.
