Professor Kimball will investigate the lattice dynamics of                      superconducting systems containing small concentrations of iron                 using Mossbauer spectroscopy.  The influence of the 3d transition               elements on superconducting and magnetic properties will be                     determined.  Vibrational states in the high temperature oxide                   superconductors will be probed with substitutions of rare earth                 ions for yttrium and of tin or ion for copper.  At a critical                   iron concentration the lattice transforms from orthorhombic to                  tetragonal.  Mossbauer and neutron diffraction will be used to                  delineate the oxygen anion order-disorder transformation between                phases of these compounds and to observe the magnetic behavior in               the disordered phase.  Neutron diffraction measurements in the                  BaPb1-xBicO3 superconductors will continue as will a search for                 other high temperature superconducting materials of the oxides                  and sulphides.
