Ultrapure Manganese 25Mn54.936 (m5N8; t5N7)
Manganese (Mn) is a chemical element with atomic number 25. It is not found as a free element in nature; but often in combination with iron and many minerals. Manganese is a metal important for industrial metal alloys.
Semiconductors with Mn belong to the group of semi-magnetic semiconductors (SMS) or diluted-magnetic semiconductors (DMS) known for their giant magneto-optical effects. The presence of Mn in SMS lattice leads to a spin-spin exchange interaction between the bound electrons, and the localized 3d electrons of Mn2+ ions. This leads to the large Faraday rotation, and application in Faraday isolators. This SMS could be used as magneto-and electro-optic sampling, and coherent acoustic phonon generation and detection. Recently, there has been interest in cadmium manganese telluride (Cd,Mn)Te as a potential material for room-temperature nuclear-radiation detection applications.
