In the present work we analyze the electronic structure of Fe4C using
the linear muffin-tin orbital (LMTO) method. The calculations were car
ried out for several lattice parameters, and the total energy calculat
ion gives the equilibrium volume, Analysis of the density of states gi
ves a good understanding of the electronic structure and magnetic prop
erties of this compound. The behavior of the magnetic moments, hyperfi
ne field and isomer shift with volume shows some similarities to the r
elated compound Fe4N.
