Stationary magic angle spinning enhanced solid state spin sensor

A magnetic field sensor comprising:

• a solid-state host containing color center defects sensitive to an external magnetic field;
• a current source to generate a first sinusoidal waveform and second sinusoidal waveform;
• a magnetic field source, in electromagnetic communication with the color center defects and operably coupled to the current source, to generate a magic-angle-spinning magnetic field in response to the first sinusoidal waveform and the second sinusoidal waveform, the magic-angle-spinning magnetic field canceling magnetic dipole interactions among the color center defects and increasing at least one of a dephasing time or a coherence time of the color center defects;
• a resonant tank circuit, operably coupled to the current source and the magnetic field source, to match an impedance of the current source to an impedance of the magnetic field source;
• at least one radiation source, in electromagnetic communication with the color center defects, to irradiate the color center defects with radiation;
• a detector, in electromagnetic communication with the color center defects, to detect a spectroscopic signature of the color center defects in response to the radiation;
• and
• a processor, operably coupled to the detector, to determine an amplitude and/or direction of the external magnetic field based on the spectroscopic signature of the color center defects.
