Studying nuclear spin in the nanoworld https://www.mpg.de/6944425/nuclear-spin-nmr-nanosamples
The structure of nanoscale samples can prospectively be examined with magnetic resonance spectroscopy. Scientists from the University of Stuttgart and the Max Planck Institute for Solid State Research and F. Reinhard and J. Wrachtrup have made it possible to use a nitrogen vacancy centre, or NV centre for short, as a detector to analyse the polarisation of nuclear spins and thus examine the structure of nanoscopic samples.
The speed of this spin around the axis depends partly on what else is surrounding
