The high‐temperature electrical properties (conductivity and thermopower) of the Co0.4Fe2.6O4‐Mn0.4Fe2.6O4 join were measured in order to determine the cation intersite distribution and establish the conduction mechanism. The cobalt and manganese site occupancies show a nearly linear composition dependence. Trivalent iron occupancies reflect the transition from an octahedral substituent (Co) to a tetrahedral substituent (Mn), but any influence on the iron distribution reaction is minimal. Small polaron conduction parameters are similar to those for magnetite and vary little across the join.
