Formation, microstructure and magnetic properties of nanocrystalline MgFe2O4

► Glycine to nitrate ratio affects the microstructural and magnetic properties of MgFe2O4. ► Rapid combustion reaction between nitrates and glycine occur around 194 °C. ► The thermodynamical considerations were taken into account to study the effect of glycine to nitrate ratio on powder characteristics. ► Spinel MgFe2O4 phase even formed at fuel lean condition.
