Structural and magnetic properties of MnxCo1−xFe2O4 ferrite nanoparticles

Structural and magnetic changes induced by high energy ball milling of CdFe2O4

“…The average X-ray density calculated from lattice constants was found to be 5.77 g/cm 3 . This is comparable to values found for similar compounds [18]. The XRD density reflects on the packing of the atoms in a unit cell.…”

“…Several articles associated with grain size dependence of the magnetic nanoparticles have appeared in literature recently [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Increased magnetic susceptibility, hyperfine magnetic fields, magnetization and Curie temperature have been observed at room temperature in nanosized ZnFe 2 O 4 produced by milling [2,3] compared to bulk samples.…”

Evolution of the Magnetic and Structural Properties with the Chemical Composition in Oleate-Capped MnxCo1–xFe2O4 Nanoparticles

“…Many synthesis methods have been proposed for the synthesis of spinel ferrites with single or multiple divalent cations, from co-precipitation to solvothermal methods . In particular, Co/Mn mixed ferrites have been synthesized by high-temperature thermal decomposition, glycothermal process, − polyethylene glycol-assisted hydrothermal method, polyol method, mechanical milling, , co-precipitation method, − ceramic method, and self-combustion. , …”

“…Indeed, in the literature, few studies reported a discussion of the magnetic properties together with the chemical composition obtained by quantitative analytical methods, such as atomic absorption spectroscopy (AAS) or inductively coupled plasma optical emission spectrometry (ICP–OES), or semi-quantitative ones, such as scanning electron microscopy (SEM)–energy dispersive X-ray (EDX) analysis. ,,,,, The crystallite size in the studied samples was found to change as a function of the Co/Mn ratio in the range of 14–22, 16–34, 23–33, , and 3.0–31.0 nm . Some studies focused on a single intermediate chemical composition. ,, Most commonly, a study of the magnetic field ,,,,,,,,,− and/or temperature dependence ,,,,,,, of the magnetization is reported, whereas only rarely an investigation of the interparticle interactions is provided .
