title: A band structure analysis of the coexistence of superconductivity and magnetism in (Ho,Dy)Ni(2)B(2)C.
abstract: The phenomenological theory of complex interplay of superconductivity and magnetism in Ho(1-x)Dy(x)Ni(2)B(2)C by Doh et al (1999 Phys. Rev. Lett. 83 5350) is based on the multi-band picture with at least one band which is strongly dominated by Ni 3d-electron orbitals. These orbitals are insensitive to the antiferromagnetic order of the (Ho, Dy) 4f-electrons, found in these alloys. In the present study we show by detailed analysis of the band structure that indeed such a band can be identified. This provides a microscopic justification of the basic idea underlying the phenomenological discussion.
