“…It was reported that the specific loss power of magnetic nanoparticles rises with increasing Ms . However, there are some conflict reports on the negative effect of Ms on the heat generation . For instance, Phong et al reported that the CoFe 2 O 4 nanoparticles with the highest magnetization and coercivity provided the lowest heat generation.…”

“…However, there are some conflict reports on the negative effect of Ms on the heat generation . For instance, Phong et al reported that the CoFe 2 O 4 nanoparticles with the highest magnetization and coercivity provided the lowest heat generation. This conflict results may be due to the high coercive values in their samples (850 Oe) which were considerably larger than the applied magnetic field; thus, their field strengths were not strong enough to activate heat generation mechanisms.…”

In the present work, Mg 0.5 Ni 0.5 Fe 2 O 4 nanopowders were prepared by a sol-gel combustion method. The magnetic properties, heat generation ability in an AC magnetic field and cytotoxicity of the mixed ferrite nanopowders were investigated. The results showed that the powders have crystalline spinel structure with a particle size in the range of 20-90 nm. Maximum saturation magnetization (Ms) of 51 emu/g was obtained for the Mg 0.5 Ni 0.5 Fe 2 O 4 nanoparticles calcined at 900°C. The results showed that, the coercivity (Hc) of the Mg 0.5 Ni 0.5 Fe 2 O 4 initially increases up to 700°C and then decreases with increasing temperature, whereas the Ms of the samples continuously increases. The Mg 0.5 Ni 0.5 Fe 2 O 4 sample exhibited a temperature increase up to 45°C during 10 minutes in the exposure of magnetic field of 200 Oe. By increasing the viscosity of ferrofluid, the heat generation ability of nanoparticles reduced up to 9% at magnetic field of 200 Oe. Cell compatibility of the ferrite powders was studied by MTT assay using MG63 cell line proliferation. MTT results showed that calcination temperature of the Mg 0.5 Ni 0.5 Fe 2 O 4 nanoparticles significantly affects the cell compatibility.

“…Among many ferrites, cobalt ferrite magnetic nanoparticles are attracting much attention because of their high coercivity, magnetocrystalline anisotropy, moderate saturation magnetization, chemical stability, wear resistance, electrical insulation, and structure [1]. Structurally, in the inverse spinel of the ferrite, tetrahedral sites are generally occupied by Fe 3+ ions, whereas octahedral sites (B-sites) are inhabited by Co 2+ and Fe 3+ ions [2].…”

In this research, structural, magnetic properties and photocatalytic activity of cobalt ferrite spinel (CoFe2O4) nanoparticles were studied. The samples were characterized by X-ray powder diffraction (XRD), energy dispersive X-ray (EDX), scanning electron microscopy (SEM), transmission electronic microscopy (TEM), Brunauer–Emmett–Teller (BET), Fourier transform infrared spectroscopy (FTIR), and UV-visible diffused reflectance spectroscopy (DRS) analysis. The XRD analysis revealed the formation of the single-phase CoFe2O4 with a cubic structure that is annealed at 500–700 °C in 3 h. The optical band gap energy for CoFe2O4 was determined to be in the range of 1.57–2.03 eV. The effect on the magnetic properties of cobalt ferrites was analyzed by using a vibrating sample magnetometer (VSM). The particle size and the saturation magnetization of cobalt ferrite nanoparticles increased with increasing annealing temperature. The photocatalytic activity of CoFe2O4 nanoparticles was investigated by using rhodamine B dye under visible light. The decomposition of rhodamine B reached 90.6% after 270 min lighting with the presence of H2O2 and CF500 sample.

“…11 In addition, the ZF showed normal spinel structure with attractive structural, morphological, and magnetic properties. [18][19][20][21][22][23][24] As a whole, this evidenced a fact that the X-ray photoelectron spectroscopy, thermal, antimicrobial, and magnetic properties were not studied at length for Co-Zn ferrite system via the citrate-gel autocombustion method. 5 Therefore, it can be expected that the zinc addition to the CF may reveal to acquire different electrical, magnetic, thermal, and antimicrobial properties.…”

“…Besides, the literature survey expressed a fact that the CoFe 2 O 4 and iron oxide superparamagnetic nanomaterials were studied for magnetic hyperthermia therapy, core/ shell structures, and different magnetic properties. [18][19][20][21][22][23][24] As a whole, this evidenced a fact that the X-ray photoelectron spectroscopy, thermal, antimicrobial, and magnetic properties were not studied at length for Co-Zn ferrite system via the citrate-gel autocombustion method. Therefore, an intension was carried out to investigate the above said properties for Co-Zn ferrite system to advance the scientific community.…”

The cobalt‐zinc ferrite (CZF) nanomaterials were prepared by citrate‐gel method, and further calcined at 600°C. The single‐phase cubic spinel structure of CZF was confirmed using the X‐ray diffraction pattern. The average crystallite size was found to be in the range of 22‐29 nm. The surface morphology was examined using the scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The average particle size of Co0.6Zn0.4Fe2O4 was determined to be 19 nm using TEM study which is supporting the average crystallite size measured from the X‐ray diffraction studies. The Fourier‐transform infrared spectra revealed the two strong absorption bands in the series of ferrites between 4500 and 500 cm−1 and these are responsible for the characteristic of spinel ferrites. The presence of elements Cu, Zn, and Co of CZF was confirmed by the elemental spectral signals of energy dispersive spectroscopy. At room temperature, the magnetic measurements of pure ZnFe2O4 and Co0.6Zn0.4Fe2O4 were evaluated based on hysteresis curves (M‐H curves). The results expressed that the addition of nonmagnetic Zn2+ ions increases the magnetic behavior in the mixed CZF samples. The antimicrobial activity of the ZnFe2O4 and Co0.6Zn0.4Fe2O4 nanoferrites was tested against harmful microbes.
