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.
