Noninvasive magnetometry based on magnetic rotation spectroscopy of oxygen.
An experimental demonstration of a noninvasive optical probe of magnetic fields is presented. The technique used is magnetic rotation spectroscopy of the b(1)?(g)(+) - X(3)?(g)(-) band of oxygen near 760 nm. Ambient concentrations of oxygen at atmospheric pressure are sufficient to observe substantial signals. In addition, a diode laser is used as the light source, making this a simple and compact measurement possibility.
