• The equilibrium atomic distributions in the off-stoichiometric Cu-Au alloyswhose high and low temperature phases are of the long period superlattice (LPS)and the Ll. (CuAu) structures respectively are investigated on the basis of themean field theory. The obtained results are as follows. LPS with uniformlydistributed excess atoms are generally unstable against the modulation of theconcentration of excess atoms along the direction perpendicular to antiphaseboundaries. The period of the concentration modulation (CM) is a half of thatof LPS and its phase shows that excess atoms enter into sites at antiphase bound-aries preferentially. CM produced by LPS increases the stability of LPS andsometimes LPS becomes stable only by accompanying CM.
