Energy band calculations were carried out for (Fe1-xMx)3Ga with x=0 or 1/12 to investigate the site preference of M atoms and the magnetic properties. It is shown that the site preference can be predicted from the total energy and is closely related to the density of states of two kinds of Fe in Fe3Ga. Furthermore it is found that the magnetic moment on Cr or Mn in Fe3Ga is antiparallel and on Co or Ni is parallel to the moment of Fe.
