The electronic structure of β-Ti6Sn5 has been studied based on the density functional theory within the local-density approximation. The calculation indicates that β-Ti6Sn5 is very close to ferromagnetic instability and shows ferromagnetic ordering after rare earth element doping. Large enhancement of the static susceptibility over its non-interacting value is found due to a peak in the density of states at the Fermi level.
