Abstract
Section titled āAbstractāNitrogen-vacancy (NV) color centers in diamond serve as a unique platform for various types of quantum sensors, including a nuclear magnetic resonance gyroscope. The fundamental sensitivity limit of a quantum sensor is closely related to the free precession dephasing time $$T_{{2n}}^{}$$ of the nuclear spin. The dependence of $$T_{{2n}}^{}$$ and transverse relaxation time $${{T}{{2n}}}$$ on the magnetic field at room temperature in the field range from 2 to 8 G is investigated, demonstrating that $$T{{2n}}^{*}$$ and $${{T}{{2n}}}$$ are not limited by the longitudinal relaxation time $${{T}{{1e}}}$$ of the electron spin projection.
