英文摘要	the b-site ordered double perovskite oxides lapbmsbo6 (m=co, ni) have been synthesized via the modified sol-gel precursor two-step route. rietveld refinements reveal strong abnormal structural distortion and bo6 octahedral deformation appearing along the ab plane. owing to the cooperative jahn-teller effect of co2+ and pb2+ ions, the co-related compound exhibits almost complete co2+-sb5+ order. for magnetic properties, spin-canted antiferromagnetic state with high extent of magnetic frustration is confirmed. the ni-related compound presents heavier magnetic frustration for introducing tiny disorder on site occupation accompanied with valence state and further enhancing the complexity of magnetic competition. dielectric measurements present a considerable temperature dependent dielectric relaxation with great dc-like loss feature in the lapbcosbo6. for lapbnisbo6, however, the permittivity with low dielectric loss is shown to be insensitive to either temperature or frequency. the corresponding electronic active energy manifests that the weakly bounded 3d-electron is prone to hop in a more distorted co-sb sublattice.
