摘　　要：An effective-field treatment for the two dimensional Isingantiferromagent-antiferromagnetic superlattice(AFAFS)without external field is pres-ented.The critical temperature dependence of the number of laycrs of superlattice cell andthe temperature dependence of magnetization of each layer in the superlattice are investi-gated.The similarity of the magnetic properties of AFAFS and those offerromagnet-ferromagnetic superlattice(FFS)is also discussed.An effective-field treatment for the two dimensional Ising antiferromagent-antiferromagnetic superlattice(AFAFS)without external field is pres- ented.The critical temperature dependence of the number of laycrs of superlattice cell and the temperature dependence of magnetization of each layer in the superlattice are investi- gated.The similarity of the magnetic properties of AFAFS and those of ferromagnet-ferromagnetic superlattice(FFS)is also discussed.
