This article presents, the systematic and successful preparation of cadmium substituted cobalt ferrite (Co1-xCdxFe2O4) nanoparticles via simple co-precipitation method. X-ray diffraction study confirmed the prepared ferrite nanoparticles were crystallized with a mono phase cubic spinel structure of Fd3m space group. The average crystallite size (Dxrd) was increased with Cd doping content, due to the replacement of Co2+ ions by Cd2+ ions. XRD pattern revealed the high intense peak corresponds to (311) lattice plane and confirmed the formation of cubic structure ferrite nanoparticles. Morphological study was done by using SEM images. The grain size found to be increased with Cd concentration and it reaches the highest of around 0.9μm for Co0.52Cd0.48Fe2O4 composition. Fourier Transform Infrared spectroscopy of prepared samples was recorded in the range of 1000-350 cm-1, confirmed the spinel structure.

“…The synthesis route, chemical composition, heat treatment, sintering temperature, type of element doped and processing condition impact the properties and grain size of the synthesized ferrite material [27]. For preparation of ferrites, several synthesis routes such as electron beam curing [28], solid state reaction method [29], sol-gel [30], co-precipitation [31][32], hydrothermal [33], high energy ball milling [34], green synthesis [35], thermal treatment [36], auto-combustion and microwave [37] have been used in the past.…”

We report effect of influence of Cd2+ ions on Co-Ni ferrites synthesized by the solid state reaction method. The X-ray diffraction analysis confirmed the cubic spinel phase with crystallite size varies between 20-24 nm. The SEM images show tetrahedral, octahedral, granular, long bulgy structures with variety of sizes. The Raman spectra for samples with x = 0.1 and x = 0.4 shown peaks corresponding to Alg, Eg and T2g which very closely match with NiFe2O4 spectra with slight variation in peak position as an effect of different chemical formula. Magnetic measurements were carried out at room temperature. It is found that substitution influenced the magnetic properties. Saturation magnetization decreased from 52.74 to 32.68 emu.gm-1 and coercivity shown an initial increase and then a continuous decrease, with increase in the Cd2+ substitution. Retentivity is found to be varying between 10.1 emu/gr - 6.21 emu/gr.

“…[9,10] Based on these properties the ferrites are used in many diverse range important application such as magnetic permanent magnets, [11] magnetic tape, [12] transformer core, [13] radiofrequency circuits and high quality filters, [14] data storage, [15] high frequency integrated inductors, [16] controlled drug delivery [17] catalysis, [18,19] gas sensors, [20] and microwave absorbing paints. [21] There are several different synthesis methods used to fabricate ferrites as reported in literatures including solgel, [22] coprecipitation, [23] mechano-chemical, [24] refluxing, [25] precursor, [26] auto-combustion and microwave, [27] and ultrasonic cavitation [28] methods.…”

The objective of this work is to synthesize cadmium doped cobalt nickel ferrite (Co0.5Ni0.5Cd1.5xFe2‐xO4) series with x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5 by co‐precipitation method and analysis of structural properties using X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) characterization. The XRD characterization of the samples confirms the cubic spinel structure. Grains in the samples are granular in nature as depicted by SEM images. The FTIR spectra of synthesized ferrites show two strong absorption bands (ν1 and ν2) in the range 400–600 cm‐1 belonging to tetrahedral (A) and octahedral (B) interstitial sites. Williamson Hall and size‐strain plot results show the variation in the grain size with change in doping concentration. Crystallite size D, lattice constant a, micro strain ε, x‐ray density Δx, dislocation density ρD, hopping lengths(LA and LB), bond lengths (A–O and B–O), ionic radii (rA and rB), texture coefficients [TC(hkl)], and mechanical properties are also reported.
