Abstract
A magnetometer with responsive material is provided that includes a PT symmetric assembly. The PT symmetric assembly includes gain material and responsive material that are positioned to achieve PT symmetry. The responsive material is configured to shift a resonance frequency of point defects in response to a magnetic field. A microwave antenna is configured to generate a microwave field of varying frequencies that engage the responsive material. A controller is configured to adjust a tunable laser source that is input into the PT symmetric assembly based on an output of the PT symmetric assembly to cause a gain generated by the gain material to match a loss caused by the responsive material. The controller is further configured to determine a strength of the magnetic field by determining one of a deviation from the exceptional point and an amplitude of the gain needed to reach the exceptional point.
