Summary on Grant Application Form |
|
It is felt now that rapid progress is beginning to be made on establishing the nature and origins of HTSC. We hope with this programme to be able to affirm at the end what was asserted at the beginning. We wish particularly to pursue further the matter of carrier-carrier scattering. This question clarly dominates the normal state transport and magnetic fluctuation behaviour above Tc, and relates directly to strong pair-breaking below Tc. Moreover it is perceived that the same interaction leads to pair formation and to HTSC itself within the two sub-system configuration which these mixed-valent, nearly localised metals present. Specifically we wish to pursue the extent to which mH-1T2 behaviour extends into non-superconducting, mixed-valent systems, and through parallel measurements on the specific heat, magnetic susceptibility, and I.R. optical properties, on bulk samples and MOCVD film, to investigate how the strength of this scattering echoes the rise and fall of Tc. These studies may be peformed on many systems, and are presently underway here on over-doped LSCO. Their extension to the fullerides and bismuthates, as well as to NCCO, etc must be checked. As a side matter we wish to continue our patterning experiments on MOCVD thin films.
