Influence of processing methodology on the structural and magnetic behavior of MgFe2O4 nanopowders

Iron Precursor Decomposition in the Magnesium Combustion Flame: A New Approach for the Synthesis of Particulate Metal Oxide Nanocomposites

“…In contrast to colloidal systems, thermal processing in dry atmospheres such as in vacuum or in O 2 provides efficient means for surface engineering of these uncapped particles without altering their structure and microstructure . Apart from applications in catalysis and photovoltaics, iron oxide containing metal oxide nanocomposites that are exposed to a rapidly alternating magnetic field can generate heat and offer strong potential for magnetic hyperthermia …”

A study of nanosized magnesium ferrite particles with high magnetic moment

“…It was shown by Smitha et al that the higher RT magnetisation was obtained when magnesium ferrite was synthesised by sol gel combustion synthesis (25.33 emu/g) in comparison to coprecipitation (4.34 emu/g) [15]. Chandradass et al obtained a RT magnetisation of 22.7 emu/g for magnesium ferrite using citrate gel method while they obtained 14.5 emu/g and 12.9 emu/g if they used reverse miscelle and coprecipitation techniques [16]. There have been some reports on the RT magnetisation values of magnesium ferrite prepared by combustion techniques which varied from 21 emu/g to 45 emu/g depending on the thermal treatment given [17][18][19].…”

Evaluation of Antioxidant and Cytotoxicity Activities of Copper Ferrite (CuFe2O4) and Zinc Ferrite (ZnFe2O4) Nanoparticles Synthesized by Sol-Gel Self-Combustion Method

“…The wide band around 3425 in Figure 2a and 3447 in Figure 2b and absorption peaks at 1652 in Figure 2a and 1633 in Figure 2b correspond to the respective hydroxyl group [41,42]. A sharp peak around 1388 cm´1 in both the spinel ferrites is attributed to the symmetric vibration of the NO 3ǵ roup [41].…”
