H. Lee et al., SENSITIVE DETECTION OF MAGNETIC-FIELDS INCLUDING THEIR ORIENTATION WITH A MAGNETOMETER BASED ON ATOMIC PHASE COHERENCE, Physical review. A, 58(3), 1998, pp. 2587-2595
An optical magnetometer based on electromagnetically induced transpare
ncy is analyzed. Utilizing the different orientation characteristics f
or different field polarizations, the magnitude and orientation of an
applied magnetic field can be measured. As a model system we consider
the sodium D-1 transition taking into account hyperfine structure and
optical pumping effects.
