Structural and magnetic properties of magnesium ferrite nanoparticles prepared via EDTA-based sol–gel reaction

Structural and magnetic properties of Gd 3+ ion substituted magnesium ferrite nanopowders

“…The low value of M r /M s is an indication of the isotropic nature of the synthesized material. These low values for M r /M s indicate the existence of an appreciable fraction of superparamagnetic particles for pure magnesium ferrite and Gd substituted MgFe 2 O 4 at Gd ratios from 0.20 to 0.30 [20].…”

“…Phase evolution and grain growth kinetics during the formation of MgGd x Fe 2 À x O 4 powders have been investigated by X-ray powder diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. Our previous studies indicated the existence of pure superparamagnetic behavior of MgFe 2 O 4 nanoparticles at room temperature for samples calcined at 400°C, using EDTA based sol gel reaction method [20]. Therefore, the impact of the Gd 3 þ ion substitution on the crystal structure and magnetic properties of the newly synthesized MgGd x Fe 2 À x O 4 nanoparticles is comprehensively studied using different physical approaches in this work.…”

Structural, AC conductivity, dielectric behavior and magnetic properties of Mg-substituted LiFe5O8 powders synthesized by sol–gel auto-combustion method

“…content upon x = 0.4. Thereafter, it was decreased with [29][30][31][32][33]. Moreover anomalous behavior of Hc was due to the different magnetic moment of Fe and Mg.…”

“…Moreover anomalous behavior of Hc was due to the different magnetic moment of Fe and Mg. This may be imputed to changes in the particle size and the low magnetic anisotropy, which arises from crystal imperfection [33,34].…”

Phase controlled synthesis of (Mg, Ca, Ba)-ferrite magnetic nanoparticles with high uniformity

“…[5] However, it is seen that the new synthesis routes is consistent with previous reports. [5,42,43] It can be inferred that the crystal imperfection reduces with the increase of grain size, [44,45] leading to the increase of Mr and Ms of the MgFe 2 O 4 magnetic nanoparticles.…”
