“…At higher frequencies, the accumulation possibilities of charge carriers drop, subsequently polarization and dielectric constant (ε′) fall gradually [ 69 ]. According to Bajaj, S., et al [ 70 ], the polarization phenomenon is similar to conduction mechanism. The presence of iron ions (Fe 2+ /Fe 3+ ) manifests ferrite materials dipolar.…”

The vast applicability of spinel cobalt ferrite due to its unique characteristics implies the need for further exploration of its properties. In this regard, structural modification at the O-site of spinel with Li1+/Zn2+ was studied in detail for exploration of the correlation between structural, magnetic, and dielectric properties of the doped derivatives. The CTAB-assisted coprecipitation method was adopted for the synthesis of the desired compositions owing to its cost effectiveness and size controlling ability. Redistribution of cations at T- and O-sites resulted in the expansion of the crystal lattice, but no distortion of the cubic structure was observed, which further supports the flexible crystal structure of spinel for accommodating larger Li1+/Zn2+ cations. Moreover, an XPS analysis confirmed the co-existence of the most stable oxidation states of Zn2+, Li1+, Co2+, and Fe3+ ions with unstable Co3+ and Fe2+ ions as well, which induces the probability of hopping mechanisms to a certain extent and is a well-established behavior of cobalt ferrite nanoparticles. The experimental results showed that Li1+/Zn2+ co-doped samples exhibit the best magnetic properties at dopant concentration x = 0.3. However, increasing the dopant content causes disturbance at both sites, resulting in decreasing magnetic parameters. It is quite evident from the results that dielectric parameters are closely associated with each other. Therefore, dopant content at x = 0.1 is considered the threshold value exhibiting the highest dielectric parameters, whereas any further increase would result in decreasing the dielectric parameters. The reduced dielectric properties and enhanced magnetic properties make the investigated samples a potential candidate for magnetic recording devices.

“…Among the oxide based materials, spinel ferrites, which can be represented by the chemical formula AB 2 O 4 , are promising to fulfill these requirements. Spinel ferrite materials have been on the radar of researchers since the late 1950s due to their excellent properties like high saturation magnetization, high coercive field, moderate remnant magnetization, low eddy current losses, and high thermal and chemical stability along with their twin properties of high electrical resistivity and good magnetic conductivity. − These varieties of properties make them good candidates for various industrial applications. − …”
