| 中文摘要 | The EPR zero-field splitting D for Fe3+ in LiTaO3 crystal has been calculated from the microscopic spin-orbit coupling mechanism and the empirical superposition model. It is found that to reach the good fit between the calculated and observed values of D, the Fe3+ ion does not occupy the exact Li+ site, but is required to move about 0.24 +/- 0.11 Angstrom in the direction of the -c axis in LiTaO3 crystal. The result is very similar to that for Fe3+ in the isomorphous LiNbO3 crystal obtained from the X-ray standing waves experiment. The reasonableness-of the Fe3+ displacement is discussed. |
