| 英文摘要 | The zero-field splittings (D and E) and the g factor of GdxEu1-xBa2Cu3O7-delta are theoretically investigated from the superposition model formulas or the zero-field splittings and the approximation formula of the g factor containing the admixtures of the ground S-8(7/2) and the excited L-6(7/2) (L = P, D, F, G) states, respectively. Based on the studies, the impurity-ligand bond angles related to the crystalline c axis in the impurity Gd3+ center are about 1.1 degrees smaller than those in the host Eu3+ site of EuBa2Cu3O7-delta. The calculated D, E, g factor and the effective magnetic moment mu(eff) show reasonable agreement with the experimental data. Particularly, the improvement for the theoretical D is achieved in the present work by considering the above angular distortion. |
