Magnetometry with Ensembles of Nitrogen Vacancy Centers in Bulk Diamond
This thesis summarizes experiments conducted to develop a high sensitivity vector magnetometer using nitrogen vacancy (NV) centers in a bulk diamond sample. This project began by analyzing the sensitivity of a single NV orientation using a continuous wave electron spin resonance approach. A protocol for determining the diamond's orientation was developed to map vector magnetic field readings in...
متن کاملLongitudinal spin relaxation in nitrogen-vacancy ensembles in diamond
We present an experimental study of the longitudinal electron-spin relaxation of ensembles of negatively charged nitrogen-vacancy (NV–) centers in diamond. The measurements were performed with samples having different NV– concentrations and at different temperatures and magnetic fields. We found that the relaxation rate T–1 1 increases when transition frequencies in NV – centers with different ...
متن کاملHigh - precision electron - spin sensing with ensembles of nitrogen - vacancy centers in diamond
This thesis describes physical background and an experimental realization of a bulk diamond magnetic field and temperature sensor. The sensing is done using continuous-wave electronspin resonance spectra of nitrogen-vacancy centers in diamond. Experiments were performed using a light-trapping diamond waveguide sample, with which we estimate to address 10" nitrogen-vacancy centers simultaneously...
متن کاملTemperature- and magnetic-field-dependent longitudinal spin relaxation in nitrogen-vacancy ensembles in diamond.
We present an experimental study of the longitudinal electron-spin relaxation time (T1) of negatively charged nitrogen-vacancy (NV) ensembles in diamond. T1 was studied as a function of temperature from 5 to 475 K and magnetic field from 0 to 630 G for several samples with various NV and nitrogen concentrations. Our studies reveal three processes responsible for T1 relaxation. Above room temper...
متن کاملMagnetic field imaging with nitrogen-vacancy ensembles
We demonstrate a method of imaging spatially varying magnetic fields using a thin layer of nitrogen-vacancy (NV) centers at the surface of a diamond chip. Fluorescence emitted by the two-dimensional NV ensemble is detected by a CCD array, from which a vector magnetic field pattern is reconstructed. As a demonstration, ac current is passed through wires placed on the diamond chip surface, and th...
