摘要：
La2-xSrxNiMn1-x SbxO6 ceramics were prepared by a conventional solid state route. The microstructures, electrical properties and dielectric properties of La2-xSrxNiMn1-x SbxO6 were investigated. The results show that a phase transition from monoclinic and rhombohedra mixed phases to single monoclinic phase occurs, and the AC conductivity decreases as Sr and Sb contents both increase. The dielectric constant and the dielectric loss of La2NiMnO6 decrease due to the Sr-Sb codoping. The activation energie of La1.96Sr0.04NiMn0.96 Sb0.04O6 are slightly lower than those of La2NiMnO6, but the pre-exponential factors are one order of magnitude lower than those of La2NiMnO6.
