%X PMN-10PT is a kind of well-known typical relaxor ferroelectrics, whose dielectrical behavior is analogous to that of spin-glass systems. Dielectric properties were studied by adding a small amount of different dopants into PMN-10PT ceramics using the normal two-step method. When doped with Li2O, the maximum dielectric constant of this material is 28640, which is higher than that of pure PMN-10PT, while the degree of frequency dispersion and DPT are decreased. When doped with CaO and Yb2O3, on the contrary, the opposite results will be obtained. In addition, the Raman spectra show that the degree of B-site order of the materials is increased when doped with Li2O and decreased when doped with Yb2O3, respectively.
