Abstract
A magnetometer includes a light source that provides excitation light and a magneto-optical defect center material with at least one defect center that transmits emitted light when excited by the excitation light. The magnetometer also includes a light sensor that receives the emitted light and a plurality of magnets that provide a bias magnetic field to the magneto-optical defect center material. The magnetometer further includes a ring magnet holder that has an outer ring with an outside surface and a plurality of holders extending from the ring. The plurality of holders hold the plurality of magnets in a same orientation with respect to one another. The magnetometer further includes a mount that has an inside surface. The outside surface of the outer ring slides along the inside surface of the mount.
