摘要
We report on electron paramagnetic resonance (EPR) studies of nitrogen doped diamond that has been (15)N enriched, electron irradiated and annealed. EPR spectra from two new nitrogen containing S = 1/2 defects are detected and labelled WAR9 and WAR10. We show that the properties of these defects are consistent with them being the < 001 >-nitrogen split interstitial and the < 001 >-nitrogen split interstitial-< 001 >-carbon split interstitial pair, respectively. We also provide an explanation for why these defects have previously eluded discovery.
