| 中文摘要 | A diagonalization (of the energy matrix for which the Hamiltonian contains the free ion, crystal-field interaction and Zeeman interaction terms) method was applied to calculate the spin-Hamiltonian parameters (g factors, g(parallel to) and g(perpendicular to), and five zero-field splittings, b(m)(n)) for the tetragonal Gd(3+) center in cubic c-RbZnF(3) perovskite. The calculated results are in reasonable agreement with experimental values. From the calculation, the defect model that the tetragonal Gd(3+) center is attributed to Gd(3+) occupying the 12-fold coordinated Rb(+) site associated with a nearest Rb(+) vacancy, V(Rb), along C(4) axis owing to charge compensation is confirmed and the defect structural data of this Gd(3+) impurity center in c-RbZnF(3) are acquired. The results are discussed. |
