Summary on Grant Application Form |

We propose to use small-angle neutron scattering (SANS) to investigate the behaviour of flux lines in superconductors (particularly High Tc materials) in the technologically and scientifically important high field region. This requires a horizontal field magnet with high parallelism of the magnetic field lines, and a large value of the maximum central field. Such a magnet is not available at present, so with we would be able to perform unique research. This magnet needs to be sited at a SANS instrument with a large flux of cold neutrons, which has a non-magnetic environment, to avoid destructive forces between magnet and surroundings. These requirements are all available via collaboration with the Paul Scherrer Institute, Switzerland. With this equipment, we shall be able to establish what changes in flux line structure accompany the changes in resistive behaviour of YBCO observed at high fields, and thereby determine whether random or correlated pinning are suitable means to suppress flux line motion and resistive behaviour at high fields. We also expect to observe effects on the flux lattice of the nature of the pairing of the electrons, and thereby provide further information about the mechanism of High- Tc super-conductivity. The cryomagnet will enable research at the high field frontier in other superconducting materials, and prove a facility for researchers into superconductors and other condensed matter systems.
