The nuclear spin is a very powerful microscopic probe: we use it as a mean of investigating magnetic order, via the nuclear spin precession in the local magnetic field. Superconductors display a characteristic behavior, which can also be investigated by NMR. Our group has developed specific instruments optimized for these kinds of applications.
