摘要：
defect structure of the tetragonal Cu2+ center in PbTiO3: Cu2+ crystal is studied by analyzing the EPR g factors and hyperfine structure constants. From the study, we suggest that an oxygen vacancy occurs in the nearest-neighbors site of Cu2+ due to charge compensation, and that the off center displacement of Cu2+ is smaller than that of the replaced host ion Ti4+. The reasonableness of the defect structure is discussed.
