| Systematic magnetic saturation moment and electrical resistivity measurements of the Fe3(1-δ)O4 and Fe3-xMxO4 (M = Ti, Zn, Al) are presented. Cation distributions for low level doping are proposed and compositional dependencies of the Verwey transition temperature are determined. The latter show striking similarities in their dependence on cation vacancies and dopant concentration for any extraneous cations. These data are the basis for the analysis of the correlation between the presented cations distributions and the Verwey transition. |
