    Notes: Abstract In spite of their layered crystal structure, the new class of intermetallic borocarbide superconductors (typified by LuNi2B2C) have three-dimensional conduction with anisotropy being a minor factor. The calculated electron-phonon coupling constants are consistent with a picture of moderate- to strong-coupling conventional superconductivity, with large contributions from boron vibrations. We report several calculated material parameters for members of this class of compounds, and compare with some of the experimental data.

    Notes: Abstract The electronic structure of idealized tetragonal Bi2Sr2CuO6 is compared with that of an orthorhombic √2×√2 model that includes atomic displacements due to the structural modulation. The electronic structure, particularly that related to Bi and O(3) atoms, is strongly modified near the Fermi energy. In particular the shape and topology of the Bi-O(3) related Fermi surfaces near the ¯M point are changed. With the modulation, bands occur near the Fermi energy over a significant part of the zone near this point. A method is proposed to distinguish between lattice distortions and antiferromagnetic correlations as the cause of recently observed shadow Fermi surfaces.
