bstract Magnesium-substituted lithium ferrite powders (Li 1− x Mg 2x Fe 5− x O 8 where x=
0.0–0.8) were prepared by sol–gel auto-combustion method. XRD profiles revealed that all
compositions were single cubic ferrite structure for the precursors annealed at 800 C for 2 h.
The crystallite size was found to decrease whereas the lattice parameter was increased with
increasing Mg 2+ ion content. The microstructure of the formed powders was Mg
concentration dependent. Increasing the Mg 2+ ion ratio was found to inhibit the grain ...
