中文摘要	The zero-field splittings (D and E) and the g factor of Gd(x)Eu(1-x)Ba(2)Cu(3)O(7-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 (8)S(7/2) and the excited (6)L(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 Gd(3+) center are about 1.1 degrees smaller than those in the host Eu(3+) site of EuBa(2)Cu(3)O(7-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.
