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.
