This study investigates the electrical transport properties of titanium-substituted Fe2MoO4 spinel oxides, specifically Fe2Mo1−xTixO4, through electrical resistivity and thermoelectric power measurements in an inert atmosphere over varying temperature ranges. The objective was to assess how varying levels of titanium substitution influence properties such as thermal activation energy, carrier concentration, and mobility. Methodologically, solid solutions were prepared by mixing stoichiometric amounts of the constituent oxides and subjected to thermal processing in a vacuum-sealed environment. The results indicate that charge carrier conduction primarily occurs through hopping mechanisms, with notable changes in the properties as titanium replaces molybdenum, leading to a decrease in the Fe2+/Fe3+ ratio, particularly in the Fe2TiO4 composition. As a result, higher resistivity and larger lattice parameters were observed in titanium-rich samples, signifying the pronounced impact of titanium inclusion on the structural and conductive characteristics of the spinel oxides. These findings contribute to a deeper understanding of the electronic behavior of substituted spinel materials for potential applications in thermoelectric devices.
