Abstract

Cation distributions in the system Fe₃O₄{single bond}CoFe₂O₄ from 600 to 1300°C were calculated from high-temperature thermopower measurements on oxygen-stoichiometric specimens. Behavior is virtually identical to that in the Fe₃O₄{single bond}MgFe₂O₄ system. Conductivity inCo_xFe_3-xO₄ (x <1) obeys the relationshipσ = [d e / (d + e)] T^{- 1} exp [14.3 - 1475 T^{- 1} (1 + 1.189 x²)],, whered ande are the octahedral Fe²⁺ and Fe³⁺ occupancies, respectively.
