Use of Hyperfine Structure of Optically Detected Magnetic Resonance Spectrum of a Single NV-Defect in Diamond in Quantum Sensorics of Weak Magnetic Fields

The possibility of using NV-defects in diamond at room temperature on nanometer spatial scales to measure magnetic fields was studied. For these purposes, samples with high concentrations of NV-centers are usually used, which increases the signal level but prevents the measurement of inhomogeneous f...

Description
Summary:	The possibility of using NV-defects in diamond at room temperature on nanometer spatial scales to measure magnetic fields was studied. For these purposes, samples with high concentrations of NV-centers are usually used, which increases the signal level but prevents the measurement of inhomogeneous fields on the scale of molecules or nanostructures. The parameters of a weak magnetic field were measured taking into account Earth's field by measuring the hyperfine structure of the optically detected magnetic resonance spectrum to calibrate and determine the resolution of a magnetic field sensor on a single NV-defect.
