CHEONG, Department of Physics and Astronomy, Rutgers University | The structure of FeSe0:88 was measured for pressures up to 7 GPa using diamond anvil cells in order to probe the changes in the lattice which coincide with change in the transport properties. These measurements are being complement by high pressure transport measurement over the same pressure range. The trends in structure and transport with pressure will be presented in order to under stand the origin of the strong pressure dependence of the superconducting transition temperature.
