“…an anode of a Li-ion battery made of NiFe 2 O 4 nanofibers can assist the electrochemical reaction since electrolytes can easily access into the anode and the empty space of pores can accommodate the volume change during the conversion reaction, resulting in a high discharge capacity. In addition, it is reported that magnetization of ferrite nanofibers can be increased to a higher value than that of nanoparticles [19,20]. Therefore, it is of great interest to study the magnetic properties of the inverse spinel ferrite of NiFe 2 O 4 nanofibers as promising ferromagnetic materials for applications [21].…”

“…Also, the specific magnetization of the samples could be influenced by the variation in percentage of magnetic material in the nanocomposites. Our values are smaller than corresponding bulk values of 47.5-80.8 emu/g, but similar with the values observed for Co-Ni ferrites nanofibers [21].…”

We report the synthesis of Co NiFe O (where x is 0, 0.25, 0.50, 0.75, 1) nanoparticles (NPs) by a wet chemical method using carboxymethyl cellulose (CMC) solution as surfactant. Their structure and magnetic properties were evaluated by X-ray diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). The gas and humidity sensing properties of the samples were also investigated. Powder X-ray diffraction analysis demonstrated the formation of face-centered cubic structure for all the samples. The average crystallite size and lattice parameters have been calculated by Rietveld refinement. The FTIR spectra of NPs confirm the presence of CMC functional groups and stretching bands attributed to the intrinsic vibrations of tetrahedral and octahedral sites of spinel ferrite. The magnetization curves of the nanocomposites at room temperature demonstrated saturation magnetizations from 21 emu/g to 58 emu/g and coercivity values between 130 Oe and 835 Oe. As not many studies have been published on this topic, the gas sensing properties of Ni-substituted Co ferrites have been evaluated. The measurements revealed that Co Ni Fe O is the most sensitive to acetone vapors.

“…Based on the comparison of the M s value with the previously reported results, all the assynthesized ferrite nanocrystals exhibit excellent magnetic properties with higher saturation magnetization. [17][18][19][20][21] Whereas, due to their small particle size and surface effects, the M s values for MFe 2 O 4 nanoparticles, as compared to those of their corresponding bulk counterparts, are lower. To confirm the superparamagnetic properties of NiFe 2 O 4 and MnFe 2 O 4 nanoparticles, ZFC and FC curves of three representative samples measured in an applied magnetic field of 100 Oe are given in Fig.…”

Three kinds of spinel ferrite nanocrystals, MFe2O4 (M = Co, Ni, and Mn), are synthesized using colloid mill and hydrothermal method. During the synthesis process, a rapid mixing and reduction of cations with sodium borohydride (NaBH4) take place in a colloid mill then through a hydrothermal reaction, a slow oxidation and structural transformation of the spinel ferrite nanocrystals occur. The phase purity and crystal lattice parameters are estimated by X-ray diffraction studies. Scanning electron microscopy and transmission electron microscopy images show the morphology and particle size of the as-synthesized ferrite nanocrystals. Raman spectrum reveals active phonon modes at room temperature, and a shifting of the modes implies cation redistribution in the tetrahedral and octahedral sites. Magnetic measurements show that all the obtained samples exhibit higher saturation magnetization (Ms). Meanwhile, experiments demonstrate that the hydrothermal reaction time has significant effects on microstructure, morphologies, and magnetic properties of the as-synthesized ferrite nanocrystals.
