The properties of advanced materials and phenomena basic to the development of new andor improved superconducting electronic technologies were studied. These include the conducting magnetic oxide strontium ruthenate relevant to high-temperature Josephson devices, the doped magnetic oxide lanthanum manganate relevant to magnetic sensing, and scanning tunneling microscopy of the superconducting energy gap in the high-temperature superconductors. We found that the transport properties of strontium ruthenate cannot be understood using the conventional theory of metals, that the spin polarized of 72 in tunnel junctions incorporating doped lanthanum manganate, and that there are intrinsic inhomogeneities in the superconducting energy gap of the high temperature superconductors on mesoscopic length scales.
