N i 2+ ions doped on M g 0.40 M n 0.60‐ x N i x F e 2 O 4 compositions with 0.00 ≤ x ≤ 0.60 have been synthesized by coprecipitation method and taken for the present work to study the dielectric properties and impedance characterization using the XRD and electrical measurements. The X ‐ray diffraction and FT ‐ IR revealed that the ferrite has single‐phase cubic spinel structure. The calculated particle size from XRD data verified using SEM as well as AFM. These photographs show that the ferrites have crystalline size in the range of 20–50 nm. It was observed that the particle size decreased and N i concentration increased. The dielectric constant and dielectric loss decreased with increase in nonmagnetic N i 2+ ions. Electrical properties indicate that synthesized nanoferrite particles have high resistivity.
