摘要: The local environment around the paramagnetic centers formed by Fe(3+) ions doped into three oxi-spinel crystals (ZnAl(2)O(4), MgAl(2)O(4), and ZnGa(2)O(4)) is investigated utilizing fourth-order perturbation formula of axial zero-field splitting parameter D on basis dominant spin-orbit coupling mechanism. In order to fix a plausible cubic space group for B-sites located Al(3+)/Ga(3+) cations, several modeling approaches are used results discussed in detail.
