Summary on Grant Application Form |
|
We will develop instruments for the detection of NMR/NQR based on optimised low Tc DC SQUIDs operated in wide bandwidth flux locked loop mode, of significantly improved sensitivity over that achieved hitherto.These instruments will be interfaced with a new ultra-low temperature facility, which has been designed to act as a platform for the proposed experiments. The nuclear refrigeration set-up will be constructed as part of this programme.We will perform a series of experiments, made possible by the capabilities of these instruments, in the area of quantum order in strongly correlated Fermi systems: (i) an investigation of 2D superfluidity of films of 3He thinner than the bulk T=O coherence length (ii) spin diffusion coefficient and possible superfluidity of 3He monolayers on smooth substrates (iii) investigation of spin dynamics near a Mott transition (iv) ground state order in frustrated 2D nuclear magnets (v) NMR on single crystals of strongly correlated metallic systems.We will also construct a broadband DC SQUID NMR spectrometer with room temperature access as a step in the development towards wider exploitation of this technique.
