Features associated with the cross relaxation between spin of the ground electric state of the nitrogen vacancy centre (NV) and other impurity spins, mainly substitutional nitrogen, N S , are observed as changes of the emission intensity as a function of external magnetic field. The features are attributed to NV-NV electron-electron spin interaction, NV- N S electron–nuclear spin interaction and NV electron spin interaction with simultaneous change of an N S electron and nuclear spin change. |
