“…This can be illustrated as, at high annealing temperatures, the intensity of diffraction peaks increased due to higher crystallinity and inactive surface layer of crystals. In contrast, the coalescence processes strengthened, facilitating the increase of grain size (23). Thus, annealing temperature plays a crucial role in governing the crystallinity and crystallite size.…”

In the current work, we have synthesized nickel substituted cobalt ferrite nanoparticles using Pechini's method. The presence of single-phase synthesized nanoparticle is confirmed at annealing temperature around 1000 oC and the crystallinity nature further improves at 1150 oC. The average crystallite size is found to increase with increasing annealing temperature. The strain in the crystalline particles also found to decrease with increasing temperature as confirmed through XRD analysis. The cuboidal morphology with considerable size is observed in nanoparticles by FESEM images. The EDAX spectrum further confirms the presence of pure single phase of desired elements in grown nanoparticles. The dielectric properties were studied using impedance spectroscopy, recorded from 100 Hz to 1 MHz at room temperature for different annealed temperatures. The change in the frequency dependent dielectric properties with increasing annealing temperature are in accordance with the Maxwell-Wagner two layers model for space charge theory and correlated barrier hopping (CBH) model.
