  Magnetic detection under high pressures using designed silicon vacancy centres in silicon carbide

  Optically detected magnetic resonance of nitrogen vacancy centres in diamond enables the detection of pressure-induced phase transitions, but interpreting their magnetic resonance spectra remains challenging. Here the authors propose implanted silicon vacancy defects in 4H-SiC for in situ magnetic phase detection at high pressures.

  Observing bulk diamond spin coherence in high-purity nanodiamonds

  The photoluminescent properties of electron spins at nitrogen–vacancy (NV) centres are promising for use in quantum information and magnetometry. It is now shown that the coherence times of NV centres in nanodiamonds can be engineered to be comparable to those of bulk diamond.
