    摘要： A method is disclosed for increasing the sensitivity of a solid state electronic spin based magnetometer that makes use of individual electronic spins or ensembles of electronic spins in a solid-state lattice, for example NV centers in a diamond lattice. The electronic spins may be configured to undergo a Zeeman shift in energy level when photons of light are applied to the electronic spins followed by pulses of an RF field that is substantially transverse to the magnetic field being detected. The method may include coherently controlling the electronic spins by applying to the electronic spins a sequence of RF pulses that dynamically decouple the electronic spins from mutual spin-spin interactions and from interactions with the lattice. The sequence of RF pulses may be a Hahn spin-echo sequence, a Can Purcell Meiboom Gill sequence, or a MREV8 pulse sequence, by way of example.

    摘要： A magnetometer for sensing a magnetic field may include a solid state electronic spin system, and a detector. The solid state electronic spin system may contain one or more electronic spins that are disposed within a solid state lattice, for example NV centers in diamond. The electronic spins may be configured to receive optical excitation radiation and to align with the magnetic field in response thereto. The electronic spins may be further induced to precess about the magnetic field to be sensed, in response to an external control such as an RF field, the frequency of the spin precession being linearly related to the magnetic field by the Zeeman shift of the electronic spin energy levels. The detector may be configured to detect output optical radiation from the electronic spin, so as to determine the Zeeman shift and thus the magnetic field.

    摘要： A solid state electronic spin system contains electronic spins disposed within a solid state lattice and coupled to an electronic spin bath and a nuclear spin bath, where the electronic spin bath composed of electronic spin impurities and the nuclear spin bath composed of nuclear spin impurities. The concentration of nuclear spin impurities in the nuclear spin bath is controlled to a value chosen so as to allow the nuclear spin impurities to effect a suppression of spin fluctuations and spin decoherence caused by the electronic spin bath. Sensing devices such as magnetic field detectors can exploit such a spin bath suppression effect, by applying optical radiation to the electronic spins for initialization and readout, and applying RF pulses to dynamically decouple the electronic spins from the electronic spin bath and the nuclear spin bath.
