    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 Self-consistent electronic structure studies show that the “extra” oxygen in the O(4) site in Hg cuprates is unlike oxygen ions in other cuprates that have been studied: it is singly charged O1−rather than being near O2−. This behavior is necesary to make a consistent interpretation of the doping behavior by oxygen in Hg cuprates. We find that the change in doping level at 9.2 GPa in HgBa2Ca2Cu3O8+δ is far too small to account for the observed rise inT c . We comment on strain effects on the electronic structure in YBa2Cu3O7.
