The nitrogen-vacancy (NV) center is the most prominent defect in diamond due to its outstanding properties as a quantum light source and its manipulable electron spin. NV applications range from quantum information processing to high sensitivity nano-magnetometry.
We present the spectroscopy of the local paramagnetic spin bath in nitrogen-15 delta-doped (111) diamond using single shallow nitrogen-vacancy centers as sensors and probe the spin bath dynamics with double spin resonance schemes.
Furthermore, we discuss recent progress in population swapping via microwave Raman transitions in the multilevel electronic ground state of the NV center.
