“…In the case of the nanoparticles, the situation is more complicated and confused because of the inversion of the cation distribution, size effects, and nonstoichiometry. If the noninverted stoichiometric nanoparticles have an antiferromagnetic ground state (T N ) 13 K) 25 like the bulk material, the ground state of nanosized inverted zinc ferrites is magnetic with a large magnetization which is generally explained by the distribution of the cations. [3][4][5]7,8,[11][12][13][14][15][16][17]20,23 Indeed, in the partially inverted stoichiometric spinel, some Zn 2+ ions occupy B-sites while some Fe 3+ ions are in the tetrahedral ones leading to a magnetically active A sublattice which strongly interacts with the B sublattice.…”

“…Values of δ ranging from 0.03 to 0.6 are reported in the literature, depending strongly upon the preparation procedures. 3,[12][13][14][15][16] ZnFe 2 O 4 nanoparticles have been synthesized with a large variety of methods: coprecipitation, 4,17,[19][20][21]23,26,27,33 microemulsion, 5,18 supercritical sol-gel processing, [12][13][14][15][16] hydrothermal synthesis, 10,25 or high-energy ball milling. 3,[7][8][9]11 The magnetization has been found to increase with grain size reduction.…”

Synthesis of nanoparticles under restricted environments offered by water-in-oil microemulsions provides excellent control over particle size and shape and interparticle spacing. These environments have been used in the synthesis of silica nanoparticles with a ZnFe2O4 magnetic core. First, aqueous magnetic fluids constituted of zinc ferrite nanoparticles with a size ranging between 4 and 6 nm have been synthesized using a soft chemical approach. Chemical analysis has shown that the zinc ferrite nanoparticles are nonstoichiometric with the estimated formula Zn 0.87Fe2.09X0.04O4 (X represents vacancies). The obtained silica nanoparticles (40-60 nm) with a zinc ferrite magnetic core (4-6 nm) have been characterized by X-ray diffraction, electron microscopy, and magnetization measurements. Preliminary magnetic measurements have inferred that the magnetic properties of these nanoparticles at low temperature are essentially governed by the interface particle-habitat.

“…Nanoscale ferrites of binary transition metals such as Zn-Ni, Zn-Mn, etc., have been reported as catalysts for alkylation of aromatics, used commercially as base material for drugs and chemicals [9,[16][17][18]. Owing to superior magnetic properties of Zn-Mn-and Ni-Zn-based spinel nanoferrites, they are potential material for magnetic cores of read-write head for recording [19]. Banerjee et al [9] have reported on catalytic performance of nanocrystalline Zn-Cu ferrite (ZCFO) for alkylation of pyridine.…”

We have synthesized zinc-copper ferrite (ZCFO) employing exploding wire technique (EWT). The X-ray diffraction (XRD) data confirm the formation of single phase spinel ZCFO, which is in good agreement with Fourier transform infrared spectroscopy (FT-IR), UV-Vis, and Raman spectroscopic analyses. It is also clearly seen in the SEM micrographs that the grains in ZCFO ferrite are very rough, which allows adsorption of gas like oxygen and therefore, the material can behave as active sensing surface. The size range of the grains in prepared sample is of 200 nm to 500 nm. The FT-IR spectrum of the nanocomposite consists of two broad bands, one at 580.4 cm−1 due to M–O stretching mode at the tetrahedral site and the other at 400.7 cm−1 due to M–O stretching mode at the octahedral site. The nanoparticles show a UV-Vis absorption band in the wavelength region of 400 nm to 700 nm. The energy band gap for the prepared nanomaterial was estimated to be 3.16 eV. Thus, the ferrite nanocomposite prepared by EWT is optically active. According to present literature, Raman spectroscopy study on zinc-copper ferrite system has not been reported till date. By suitable attributing various Raman modes, we have further confirmed the formation of ZCFO nanophase through the present novel approach.
