One of the vastly studied magnetic material magnetite (Fe 3 O 4) belongs to the family of spinel ferrites due to its high Curie temperature T C (∼859 K), half-metallicity, tunable magnetic properties, large room temperature spin-polarization and well-defined anisotropy. There are few well-known half-metals which possess full spin-polarization along with high T C.
