Summary on Grant Application Form |

This is a proposal to use NMR to study the quantum fluids 3He and 3He-4He in a silica-aerogel matrix under combined conditions of very high magnetic field B and very low temperature T. The overall plan is for Professor Candela to bring a suitable aerogel-filled NMR cell to Nottingham for new experiments on the 11.5 T demagnetisation cryostat. One objective of the present proposal is to study the effect that a nearly fully polarised, localised He-3 layer on the aerogel surface has He-3 superfluid with the aim of discovering more about the nature of the order parameter. The spin dynamics of normal He-3 will be investigated. NMR relaxation times will be measured and we shall look for evidence of spin rotation effects that have been observed in bulk He-3. If there is time during the visit, we will add small amounts of 4He to the cell in order to displace the localised He-3 layer. In these very high field experiments one expects this will have a dramatic effect on the order parameter.
