Advanced pulse techniques in nitrogen-vacancy colour center spin manipulation

Nitrogen-vacancy colour centers have some interesting properties, that make them useful, inter alia, in magnetometry. For future applications it’s crucial to measure relaxation times of spin polarisation. It’s also possible to enlong transverse relaxation time by limiting influence of some factors on the rate of decoherence. To achieve this, two-dimensional pulse techniques were used which allowed to obtain T2 times around 1 ms, what is impressive for a solid in room temperature. Better reconstruction of polarisation in time may be useful in practical applications of NV centers in magnetometry such as nuclear magnetic resonance.
