“…The effects of the escaped gases during the combustion phase could be the formation of the voids in the powdered samples. Similar findings were also seen in other studies [19,20,21]. EDAX analysis for Zn-ferrite, shown in Figure 4, indicates that the basic compositions of the samples are Zn, Fe and O. Al impurity peak appears in EDAX pattern of Zn-ferrite powder with 0.33 G/N ratio due to the sample coating.…”

We report the influence of different glycine-to-nitrate ratios on the physical and magnetic properties for synthesized zinc-ferrite by microwave-assisted combustion route. Phase impurity and surface morphology investigated with XRD analysis and field emission- scanning electron microscopy, indicated that spinel structure were formed.Average particles size increased with the decrease of glycine to nitrate ratio. Magnetic measurement results indicated that high values of saturation magnetization were produced with low glycine/nitrate ratio. Optical properties of the investigated ferrites exhibited photo absorption from UV to visible region with energy gap values that decreased with the decrease of glycine-to-nitrate ratio. Mainly two broad metal-oxygen bands for zinc-ferrite were seen in FT-IR spectra.

This study aimed to synthesize the nickel (Ni) doped cobalt ferrite (CFO) nanoparticles and to determine its anticancer effect on breast cancer MCF‐7 cells. The various concentrations of Ni (0.2%, 0.4%, 0.6%, 0.8%, and 1%) doped CFO nanoparticles were synthesized using Coriandrum sativum extracts by precipitation technique. The synthesized Ni‐CFO was characterized by X‐ray diffraction, Fourier transform infrared spectroscopic, transmission electron microscopy, and vibrating sample magnetometer analyses. The results show that 0.8% Ni‐CFO nanoparticles showed good magnetic properties and antioxidant activity than other concentrations of Ni‐CFO. The results showed that the administration of 0.8% Ni‐CFO nanoparticles promoted apoptosis, and reduced cell adhesion and migration of MCF‐7 cells, as demonstrated by increased lipid peroxidation, decreased antioxidant levels such as superoxide dismutase, catalase, and glutathione peroxidase, and increased formation of reactive oxygen species. Moreover, administration of 0.8% Ni‐CFO nanoparticles decreased the Bcl‐2 expression while activating the expression of p53, Bax, and cleaved caspase 3, 8 and 9 protein expression. Notably, 0.8% Ni‐CFO treatment reduced phospho‐PI3K, phospho‐Akt, and phospho‐mTOR expression levels. As a result, via altering apoptotic related proteins, 0.8% Ni‐CFO induced cell death. Therefore, the 0.8% Ni‐CFO could be utilized to treat breast cancer.

“…In spinel ferrites there are three types of magnetic interactions between the metallic ions mediated by oxygen anion (super-exchange mechanism), known as A-A interaction, B-B interaction and A-B interaction. It has been observed experimentally that the interaction energies are negative [16], therefore inducing an anti-parallel orientation. The strength of super exchange interaction energy depends upon angle between Me 2+ -O-Fe 3+ and the distance from these ions to the oxygen as shown in Fig.…”

In the present work, we have focused on crystal structure, magnetic properties, M-H curve, superparamagnetic behavior and magneto-crystalline anisotropy of soft ferrimagnetic oxides having spinel structure. Due to their unique magnetic properties such as high Curie temperature and high saturation magnetization, spinel ferrites offer opportunities for applications in different fields such as hyperthermia, targeted drug delivery, magnetic resonance, microstrip antenna. Various applications of these ferrites have been discussed and explored due to possibility nano-size material synthesis.
