摘要
The electron paramagnetic resonance parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to)) of PbTiO(3): Cu(2+) are calculated from the complete diagonalization method and the perturbation theory method. The calculated results obtained by the complete diagonalization method are close to that obtained by the perturbation theory method, and in good agreement with the experimental values. In the complete diagonalization method, the complete diagonalization procedure is established based on the 3d(9) electron system in tetragonal field. From the calculation of the electron paramagnetic resonance parameters, the local defect structure of the [CuO(6)](-10) cluster can be determined as D(4h) with R(x) = R(y) = 0.1952 nm, R(z) = 0.2076 nm.
