Abstract
The cation distribution in the spinel ferrite system NixMn1-γ-xFe2+γO4 (x = 0, 0.25, 0.5, 0.75 and γ = 0.137) has been calculated analytically in complete form as a function of thermodynamic parameters. A generalized theoretical framework based on the O’Neill–Navrotsky model and Newton methods was used to solve a multicomponent system for up to 10 cation species. The relationship between the cation distribution and composition is given. The results are shown to agree with the available experimental results.
