Longitudinal 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 ...

13C hyperfine interactions in the nitrogen-vacancy centre in diamond

The electronic spin associated with the nitrogen-vacancy (NV) centre in diamond interacts with an environment formed by isotopic impurities and paramagnetic defects; the strength of these interactions depends on the location of each impurity relative to the NV centre. From the electron spin resonance spectra of individual NV centres we infer the possible values and signs of hyperfine splittings...
