Abstract

The electronic structure of Y $_{4}$ Co $_{3}$ has been studied based on the density functional theory within the local-density approximation. The calculation indicates that Y $_{4}$ Co $_{3}$ is very close to ferromagnetic instability. The Fermi surfaces are composed mainly of 3d electrons of Co and 4d electrons of Y.
