dc.description.abstractThe characteristic properties of polycrystalline (Sr,Fe)TiO3 ceramics have been studied through Mössbauer, EPR, IR and differential scanning calorimetry because perovskite type dielectrics have useful applications in electronic industry. In Fe-doped materials, the small concentration of Fe atoms provides active centres that can be probed through Mössbauer and EPR methods which are precise enough to detect small lattice structural perturbations and yield valuable information. The present work deals with their dielectric properties including dielectric relaxation time that is considered an important study from a theoretical angle. It is found that the two-state Debye relaxation model is inadequate. These ceramics tend to behave like relaxors with ferroelectric transition temperature in the range 200-250°C depending upon iron concentration.en_US
