The nonstoichiometry of spinel ferrite (Mg x Fe 1؊x ) 3؊ O 4 has been measured as a function of oxygen activity (a O2 ) and Mg content (x) at 1000°C via coulometric titration. For a given Mg content, the nonstoichiometry varies with the oxygen activity as O2 , indicating metal vacancies at high a O
