Magnetite - Wikipedia

Biomagnetism is usually related to the presence of biogenic crystals of magnetite, which occur widely in organisms. These organisms range from bacteria (e.g., Magnetospirillum magnetotacticum) to animals, including humans, where magnetite crystals (and other magnetically-sensitive compounds) are found in different organs, depending on the species. Biomagnetites account for the effects of weak magnetic fields on biological systems. There is also a chemical basis for cellular sensitivity to electric and magnetic fiel…Controlling magnetization direction of magnetite at room,,Nov 17, 2020· After applying an external voltage, lithium ions flow through the reduction-oxidation transistor and reach the bottom magnetite film, altering its charge carrier concentrationMagnetite - an overview | ScienceDirect Topics,Quantum mechanics has helped establish discrete changes in magnetic moments that can occur. The orientations of magnetic moments in the crystals are either parallel or anti-parallel to the applied magnet field. Magnetite is ferrimagnetic with a Curie temperature of 850 K and magnetism of about 4
