Abstract
Section titled âAbstractâIn this work we use fluorescence from nitrogen-vacancy defects in diamond to\ndetect and explore other paramagnetic defects in the diamond, such as P1\ndefects, which are commonly undetectable through optical detection of magnetic\nresonance in standard conditions. Our method does not require overlap between\nthe defectsâ resonances and therefore is applicable in a wide region of\nmagnetic fields and frequencies, as verified by excellent fit to theoretical\npredictions. We propose a depolarization scheme of P1 defects to account for\nthe observed data. To verify our results, we perform cavity-based detection of\nmagnetic resonance and find a good agreement between the measured optically\ninduced polarization and the value obtained theoretically from rate equations.\nThe findings in this work may open the way to detection of paramagnetic defects\noutside of the diamond through the photoluminesence of nitrogen-vacancy\ndefects, which might be useful for imaging in biology.\n
