Manganese Iron Oxide (MnFe2O4) Nanopowder / Nanoparticles

Manganese iron oxide nanopowder / nanoparticles also known as manganese ferrite, is a type of spinel ferrite compound that combines manganese (Mn²⁺) and iron (Fe²⁺ and Fe³⁺) in its crystal structure. The general formula for manganese iron oxide is MnFe₂O₄, where manganese and iron atoms occupy the octahedral and tetrahedral sites within the spinel lattice structure.
