Abstract
Band properties of the quaternary superconductor C (≊17 K) and related intermetallic phases (including, for example, LuNiBC and C) have been calculated in the local-density approximation via the linear augmented-plane-wave method. The results feature a density-of-states peak near the top of nearly filled Ni(3d) bands, with only modest B and C orbital admixture. The calculated C bands suggest that these interesting boride carbide phases represent a family of conventional (rather than high-) superconductors.
