Synthesis and morphological study of chromium substituted Zn–Mn ferrites nanostructures via sol–gel method

Effects of Mn ions on structural and Mössbauer properties of nanoferrites Zn1-xMnxFe2O4 by sol-gel combustion method

“….Where (hkl) is Miller index, d is crystal plane spacing. With the continuous increasing of Mn 2+ ions concentration, the lattice constant gradually increased, and this result is consistent with the previous mentioned [14][15][16], because the ionic radius of Mn 2+ (0.91Å) are larger than the ionic radii of Zn 2+ (0.82Å). The figure 2 shown, a obvious displacement of the peak position to smaller angles is observed for the (311) reflection peak, indicating a decrease in the lattice parameter.…”

Dielectric relaxation, conductivity behaviour and magnetic properties of Mg substituted Ni–Li ferrites

“…The gel was dried at 383 K and then it was ignited to form loose powder. The as prepared powder was annealed at 1073 K to obtain nanosized crystalline powder [14][15][16][17][18]. X-ray diffraction patterns of the annealed ferrites were recorded using Miniflex-II Xray diffractometer (Rigaku).…”

Chemical synthesis, structural and magnetic properties of nano-structured Co–Zn–Fe–Cr ferrite

“…The physical properties of the nanomaterials are predominantly controlled by the grain boundaries than by the grains [6]. The nanoparticles of ferrite can be prepared by various techniques such as citrate-nitrate combustion method [7], sol-gel route [8], pulsed laser ablation [9], and solvothermal process [10]. Ferrites, by virtue of their structure can accommodate a variety of cations at different sites enabling of wide variation in the electrical and magnetic properties.…”
