Studies on morphological and electrical properties of Al incorporated combusted iron oxide

▶ The pure and Al doped iron oxide samples were prepared by combustion route. ▶ Micrographs depict the samples are compact and homogeneous with varying grain sizes. ▶ The dielectric behavior shows the electronic polarizability at higher frequencies. ▶ Frequency dependence of dielectric permittivity shows Debye dielectric dispersion.
