Magnetism In Spinel

By using a superexchange mechanism, the unpaired spins of metal ions are coupled through shared oxide ions.

In ferrite spinels, electron spins at tetrahedral sites have one orientation, while electron spins at octahedral sites have the opposite orientation. If the number of spins in these two types of sites is the same, the spinel is antiferromagnetic. If not, it would be ferromagnetic.

Anti-ferro magnetic substances show weak magnetism, whereas diamagnetic substances show no magnetism at all.

Spinel ferrite's structure exhibits exceptional multifunctional properties such as excellent magnetic properties, a high specific surface area, surface active sites, high chemical stability, tuneable shape and scale, and functionalization options.

The inherent properties of CoFe2O4 NPs make them excellent candidates for biomedical nanotechnology. They are made using various synthesis methods, which affect their properties. CoFe2O4 NPs and their related applications are highly regarded in biotechnology and bioengineering.

With more than a decade of marketing experience, I am now based in Bangkok where I combine my professional background with a long-standing passion for gemstones. I write articles that explore both the beauty and the business of gems, offering insights into their history, trade, and market dynamics. My goal is to make the world of gemstones more accessible to anyone curious to learn, while bringing in the perspective of someone who understands both storytelling and strategy.
