Abstract
Section titled āAbstractāWe present an experimental study of the longitudinal electron-spin relaxation of ensembles of negatively charged nitrogen-vacancy (NVā) centers in diamond. The measurements were performed with samples having different NVā concentrations and at different temperatures and magnetic fields. We found that the relaxation rate $T_{1}^{-1}$ increases when transition frequencies in NVā centers with different orientations become degenerate and interpret this as cross-relaxation caused by dipole-dipole interaction.
