Electrical transport properties. (a) Resistivity as a function of temperature of 40 nm Fe3O4 thin films grown on MgO (001), Co2TiO4 (001), Co1.75Mn0.25TiO4 (001) and Co1.25Fe0.5Mn0.25TiO4 (001) substrates and of single-crystal bulk Fe3O4. (b) The Verwey transition temperature (TV+) as a function of film thickness of the films grown on MgO (001), Co2TiO4 (001), Co1.75Mn0.25TiO4 (001) and Co1.25Fe0.5Mn0.25TiO4 (001) substrates, the black horizontal line represents the TV+ of a stoichiometric bulk magnetite crystal.
