• A modified I11C2LI] field tlveory is ajcplied to five axial next nearest-neiglabor Ising(ANNNI) naodel, xx'ltere tlve model is treated exactl)' aloutg tlte directiou? of comjaetingaxial interactioxas wl?i1e tits mean field a)cproxinvalioxa is naade w'it]?in the fer-romagnetic layer. Particular attention is paid to the )cartially disordered states and t1?easynametric states, xx'ltich are predicted to be stabilized by the rnean field theory if theixatralayer interactioxa is weak. Botlt nttmc:rjcal auad amtalytical calculatiotts are made tofind tlvat neither tlae partially' disordered states nor the as)'mmetric states are stabilizedbut only the conventional ordered states are stable.ANNNI naodel, modulated structures, jcartially disordered states
