| 中文摘要 | The trigonal distortions of Ni2+, V2+, Mn2+ and Co2+ ions in ZnSiF6. 6H(2)O crystal have been studied by analysing their zero-field splittings and the anisotropy of g factor (characterized by Delta g = g(perpendicular to) - g(parallel to)) From the studies, it is found that the sign of trigonal distortion (compression or elongation) of octahedral environment of impurity ion is impurity-dependent, i.e., when the ionic radius of impurity is greater than that of the replaced Zn2+ ion, the octahedral environment of impurity is compressed, whereas if the ionic radius of impurity is smaller than that of Zn2+, it is elongated. This point is similar to the case of isomorphous pure crystal where the paramagnetic ion is the host ion rather than the impurity. |
