Abstract: Complex oxides replaced by rare earth ions, Eu0.5RE0.5Fe0.5Mn0.5O3(RE=La, Pr,Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb) were prepared by the solid state reaction method.Measurements by XRD and XPS were carried out. The study of XPS indicates that the replacement by rare earth causes the decrease of the binding energy(B. E. )of rare earth ions,compared to their sequioxides. And in the replaced oxides, the binding energy of Fe2p3/2and Mn2p3/2 increases with the decrease of ion radius of REion. The reasons for the changes of B.E. are discussed.
