  Some recent neutron scattering works on CeRhIn5 and Ce2RhIn8, together with
related resistivity and specific heat measurements, are summarized. In spite of
its layered crystal structure, CeRhIn5 is shown to be 3-dimensional both
magnetically and in transport. We also find that the Fisher-Langer behavior is
closely followed in CeRhIn5. This may circumvent the Kondo lattice model and
support applying established Fermi-liquid superconductivity theory to heavy
fermion superconductors.
