Dielectric and magnetic properties of Fe-doped CdTiO₃ ilmenite ceramics

Fe-doped CdTiO₃ powders were synthesized using the sol–gel method with new precursors and titanium tetraisopropoxide. The samples were characterized by X-ray diffraction (XRD), which confirmed that all samples exhibited the ilmenite structure, along with secondary traces of TiO₂ and CdO phases. The ratios of these secondary phases varied with different Fe concentrations. The effects of iron substitution on the ferroelectric properties of Fe-doped CdTiO₃ ilmenite samples were studied through dielectric and magnetic measurements. Vibrating sample magnetometer (VSM) measurements indicated significant changes in the magnetic properties of Fe-doped CdTiO₃ ilmenite, revealing that both the coercive field (HC) and remanent magnetization (MR) decreased with increasing Fe concentration.
