Cation Distribution and Magnetism in Quenched ZnFe2O4

A comparative study of spinel ZnFe2O4 ferrites obtained via a hydrothermal and a ceramic route: Structural and magnetic properties

“…The peaks at 1020.99, 1044.11 eV and 1021.68, 1045.04 eV can be ascribed to the tetrahedral (tet) A sites and the octahedral (oct) B sites, respectively. Generally, Zn 2+ ions strongly prefer to occupy A sites, while they were also reported to occupy B sites [16,17]. The similar results can be seen in Fig.…”

“…temperature should be a key factor for the site occupancy of Fe 3+ [16,17]. In this study, we prepared the ZFO specimens via a hydrothermal method and a traditional ceramic method, respectively, and proved that the Zn-deficiency can also cause the transition of magnetism from antiferromagnetism to ferrimagnetism in ZFO.…”

“…Therefore, if partial Fe 3+ ions in B sites are forced to locate in A sites, the magnetism in ZFO could transform from antiferromagnetism to ferrimagnetism. This is instructive to the study of magnetism in spinel structures, and consequently the magnetism in ZFO also aroused the interest of some researchers [16][17][18]. It has been proved that the sintering…”

Effect of the degree of inversion on optical properties of spinel ZnFe2O4

“…Mozaffari et al 23 and Yuan et al 24 reported that the magnetization of ZFO increases as the degree of inversion becomes larger. Harris et al 25 reviewed the effect of the degree of inversion of mechanochemically processed ZFO nanoparticles not only on the magnetization but also on the Néel temperature and the nuclear magnetic properties, including hyperfine field distributions, isomer shifts, and quadrupole interactions.…”
