摘要：

The anisotropy of the Fermi velocities and the orbital character of various parts of the Fermi surface of rare earth (R) transition metal (T) borocarbides RT2B2C (T = Ni, Pd, Pt, etc.) are investigated by full-potential relativistic band structure calculations. Their relationship to the anisotropy of the upper critical field and the coexistence of magnetism and superconductivity is discussed on a qualitative level within the multiband Eliashberg theory.
