Band structures of the pressure-induced, heavy-fermion superconductorCe2Ni3Ge5 and its non-superconducting, mixed-valence isostructural (Ibam)counterpart Ce2Ni3Si5 have been calculated employing the full-potentiallocal-orbital code. Both the local density approximation (LDA) and LDA+Uapproaches were applied. These investigations were focused particularly on thetopology of the Fermi surfaces (FSs) of the compounds. The results show thatthe FSs are quite similar in these systems and exist in four bands, containingthree-dimensional holelike and electronlike sheets. However, the specific FSnesting properties has been revealed only in Ce2Ni3Ge5. They support apreviously postulated presence of antiferromagnetic spin fluctuations (SF) inthe heavy-fermion superconducting state of this germanide under pressure. SuchSF can be responsible for the pressure-induced unconventional superconductivityin this system.
