“…It eliminates exchange (B-B) and super exchange (A-B) interactions [26,57]. Similarly, same result was got for Mo doped ferrite nanoparticles [37,40,41]. For the present method, the exceptionally low magnetization values derive from two sources.…”

In the current research, Cu0.5Co0.3Mo0.2Fe2O4 mixed ferrite nanoparticles have been synthesized using Co-precipitation method. XRD patterns show the development of polyphasic copper, cobalt and molybdenum mixed spinel composition. The particle size of ferrite system is 16nm and they are nanoparticles. The lattice constant was determined to be 8.368 Å used for the highest peak (311). FTIR spectroscopy shows the lower octahedral and higher tetrahedral frequency alignment of ions in the spinel ferrite leading to the octahedral 550 cm− 1 and the tetrahedral 471 cm− 1 vibration modes. TEM micrographs showed spherical morphology and their particle size less than 50 nm, which correlated XRD crystallite size. VSM shows excellent ferrimagnetic properties because of higher coercivity (985.29 G). These higher coercivity materials can make cathode content for Li-ion batteries.

“…The coercivity first increased for x=0.02 from 134.60 to 177.06 G while the particle size decreased from 94.5 to 88.7 nm. This behavior can be explained by the inverse relationship between H c and the particle size in the case of a multidomain structure where H c increases when the particle size decreases [32]. Also, H c is related to anisotropy energy that in turn depends on the shape, surface, magnetoelastic and magnetic anisotropy.…”

In this study, Y3-xCdxFe5O12 (0.0 ≤ × ≤0.2) powders were synthesized via the co-precipitation method at calcination temperature 1100 °C. The phase formation of YIG was confirmed from X-ray powder diffraction (XRD) and Fourier Transform Infrared (FTIR) technique. The change of the band-gap energy, determined from the analysis of UV-visible spectroscopy, with the particle size was in agreement with the quantum confinement effect for x between 0.02 and 0.2. The magnetization study showed a non-monotonic change in the saturation magnetization and the coercivity with the increase of Cd2+ content. This behavior is an indication of both effect of particle size and the concentration of the doped Cadmium. The Mӧssbauer spectroscopy analysis confirmed the existence of Fe3+ in both octahedral and tetrahedral sites and the non-existence of Fe2+.
