“…It is widely used to produce both equilibrium and non-equilibrium materials including nanostructured, amorphous, alloys, composites, and spinel soft ferrites [3,[9][10][11]. Yang et al [13] have reported a formation of Ni-ferrite via the mechanochemical and subsequent heat treatment. They also investigated the effect of heating temperature on the grain growth activation energy and crystallite size variation.…”

An investigation of the formation of Ni-ferrite from a powder mixture of NiO and Fe 2 O 3 by high-energy ball milling combining X-ray diffraction and differential scanning calorimetry (DSC) is presented. The XRD results indicate that the NiO/Fe 2 O 3 particles reacted in a selfsustaining combustion mode, producing nickel ferrite particles ranging from 5 to 18 nm in size after 18 h of milling. The DSC traces present a broad exothermic reaction peak at the temperature range of 200-1,000°C, with a big mountain-peak around 672°C, of the as-received powder mixture. It shifts from 672 to 647°C by increasing milling time to 18 h. The onset temperature of the transition is in the range of 736-844°C for milled samples between 6 and 18 h. The transition is assigned to the re-crystallization of the nanocrystalline samples. The Curie temperature of Niferrite is also observed in the DSC traces for the 18 hmilled sample, suggesting the Ni-ferrite formation. The performed thermogravimetry for this sample indicates the no mass changes, whereas for as-received powder mixture the mass change is about 1.2 %. FT-IR spectra shows two absorption bands in the Ni-ferrite structure around 400 and 600 cm -1 , which are attributed to octahedral and tetrahedral sites, respectively.

“…They are interesting due to their size-dependent optical, electronic, magnetic, thermal, mechanical, and chemical properties. In the last years there is a strong interest in ferrite nanoparticles due to the fact that nanoscale materials possess properties that are comparable to, or superior to those of bulk materials counterparts [1], to the possibility of analyzing the fundamental aspects of magnetic ordering phenomena in magnetic materials with reduced dimensions [2], as well as its potential applications in high density data storage, magnetic sensors, spintronics, magnetic resonance imaging, ferrofluids, magnetically guided drug delivery, or microwave devices [3].…”

Abstract. Nickel ferrite nanoparticles were prepared by a modified sol-gel technique employing coconut oil, and then annealed at different temperatures in 400-1200 ºC range. This route of preparation has revealed to be one efficient and cheap technique to obtain high quality nickel ferrite nanosized powder. Sample particles sizes obtained with XRD data and Scherrer's formula lie in 13 nm to 138 nm, with increased size with annealing temperature. Hysteresis loops have been obtained at room temperature with an inductive method. Magnetic field induced microwave absorption in nanoscale ferrites is a recent an active area of research, in order to characterize and explore potential novel applications. In the present work microwave magnetoabsorption data of the annealed nickel ferrite nanoparticles are presented. These data have been obtained with a system based on a network analyzer that operates in the frequency range 0 -8.5 GHz. At fields up to 400 mT we can observe a peak according to ferromagnetic resonance theory. Sample annealed at higher temperature exhibits different absorption, coercivity and saturation magnetization figures, revealing its multidomain character.
