FIELD: measurement.
SUBSTANCE: invention relates to measurement of external magnetic field induction. Quantum magnetometer based on N2V-centres in diamond contains a solid-state active element in the form of a diamond sample with impurity-defective N2V-centres in a neutral charge state (H3 colour centres), consisting of two nitrogen atoms and a vacancy, having different charge states and emitting different spectral wavelengths, and an optical pumping source in the range of the phonon absorption wing of N2V-centres.
EFFECT: creation of a quantum magnetometer based on N2V-centres in diamond with increased sensitivity, the use of which does not require cooling of the diamond sample to cryogenic temperatures.
