This research work explored the synthesis and characterization of magnetic manganese ferrites using a simple combustion method. The purpose of creating the magnetic manganese ferrites was for their planned use as ozonation catalysts. Their magnetic properties allow for their recovery from the treatment system. Magnetic manganese ferrites were prepared by mixing manganese nitrate and iron nitrate in a stoichiometric ratio of 1:2. Polyvinyl alcohol was added to the mixed metal salt solution and the ratio of PVA: total nitrate salt added was varied from 1:1 up to 1:2 by weight. The resulting particles were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), tunneling electron microscope (TEM), and Ultraviolet-Visible spectroscopy (UV/Vis).

Ferromagnetism
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Magnetic Susceptibility and Permeability
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...
