An atomic magnetometer is used to detect radio frequency magnetic fields, such as those generated in nuclear resonance experiments. The magnetometer is based on nonlinear magneto-optical rotation and pumps an atomic vapor into a quadrupole aligned state. Detection of the modulation of the polarization of a linearly polarized beam provides the radio frequency signal, which can then be processed to extract the component frequencies.
