“…The change of unit cell volume with grain size for Zn 0.86 Fe 2.14 O 4+δ NPs is different from the critical size behavior observed for other nano‐oxides. The rapid decrease of unit cell volume is attributed to mixed occupation of Fe 3+ ions at tetrahedron (r 1 (Zn 2+ )=0.60 Å, r 1 (Fe 3+ )=0.49 Å) and octahedron site (r 2 (Zn 2+ )=0.74 Å, r 2 (Fe 3+ )= 0.55 Å) of cations [36] . When the mixed occupation of Fe 3+ ions was inhibited at 220 °C, the cell volume increased again.…”

Herein, non‐stoichiometric zinc ferrite nanoparticles, Zn0.86Fe2.14O4+δ,with grain sizes of being smaller than 11 nm were successfully prepared by varying the hydrothermal reaction duration and temperature. The influence of reaction temperature and time on the grain size of zinc ferrite nanoparticles was investigated. Non‐stoichiometric zinc ferrite nanoparticles underwent distinct processes at different reaction temperatures: at 200 °C, the growth mechanism follows an Ostwald ripening model with activation energy 124.7 kJ/mol, while at 120 °C, the particle growth is governed by aggregation and coalescence, Ostwald ripening mechanism with the activation energy 27.5 kJ/mol and digestive ripening process.The abnormal growth behavior of zinc ferrite nanoparticles is completely different from previous reports on the oxides. Detailed analysis of XPS, XRD, FT‐IR and Mössbauer spectra revealed that the presence of rich iron oxides on the surface of nanoparticles is responsible to the non‐stoichiometry. Moreover, unit cell volume and magnetic property of non‐stoichiometric zinc ferrite exhibited two extremum as the increase of grain size, which was closely related to the grain size‐dependent structure changing. The unusual growth behavior and the size dependent structure and property changes of non‐stoichiometric zinc ferrite nanoparticles reported in this work may be beneficial to guide the future development of magnetic materials.

“…The magnetic properties of nanomaterials, associated with the spin of electrons, make them suitable for various applications in biotechnology, telecommunications and electronic industries. The magnetic properties of cubic spinel ferrites depend upon their metallic composition, particle size and cationic distribution between tetrahedral (A) and octahedral (B) sites [7,21]. In case of magnetic NPs, the presence of large number of atoms at the surface due to high-surface-to-volume ratio and finite size effects result in several interesting and superior properties compared to bulk materials [22].…”

Engineered nanomaterials with tailored properties are highly required in a wide range of industrial fields. Consequently, the researches dedicated to the identification of new applications for existing materials and to the development of novel promising materials and cost effective, eco-friendly synthesis methods gained considerable attention in the last years. Cobalt ferrite is one of the nanomaterials with a wide application range due to its unique properties such as high electrical resistivity, negligible eddy current loss, moderate saturation magnetization, chemical and thermal stability, high Curie temperature and high mechanical hardness. Moreover, its structural, magnetic and electrical properties can be tailored by the selection of preparation route, chemical composition, dopant ions and thermal treatment. This chapter presents the recent applications of nanosized cobalt ferrites doped or co-doped with divalent transition ions such as Zn 2+ , Cu 2+ , Mn 2+ , Ni 2+ , Cd 2+ obtained by various synthesis methods in ceramics, medicine, catalysis, electronics and communications.
