Abstract Cu ferrite and In substituted Cu ferrite has been successfully synthesized (In x Cu 1−x Fe 2 O 4 ; x = 0.0, 0.2) at pH 11 and sintered at 300 °C, 600 °C, 900 °C. From the XRD analysis, the ferrite phase is confirmed and particle size varied from 28 to 37 nm owing to sintering temperature. TEM microstructure confirms that samples having polycrystalline nature because of superimposition of bright spots. FT-IR spectra exhibit general behaviour of ferrite. The significant change of dielectric constant has been noticed from dielectric measurement while substitution of In element. The room temperature magnetic measurements demonstrate a solid impact of sintering temperature and In substitution on saturation magnetization and coercivity.
