- noun A steel-gray to black mineral, MnO(OH), found in North America and Europe; manganese oxide.

- noun A hydrated oxid of manganese occurring in orthorhombic crystals of a steel-gray or iron-black color and brilliant luster, also in masses having a columnar structure. It is often altered, by loss of water, to pyrolusite. Also called
gray manganese ore.
- noun A substance which may be viewed as a compound of manganese dioxid with the monoxid of a more basic or electropositive metal.

The sesquioxide is found crystallized in an anhydrous form in braunite, and hydrated in manganite.
Like iron ores, manganese ores consist principally of the oxides of manganese (pyrolusite, psilomelane, manganite, wad, and others), and rarely the carbonate of manganese (rhodochrosite).
Using cutting-edge spectroscopy at atomic resolutions, researchers led by David A. Muller, professor of applied and engineering physics, have figured out why this happens, and how to grow ultra-thin manganite films while retaining their magnetic properties.

The key is understanding how to grow perfect, defect-free manganite sheets.
A metal oxide complex called lanthanum strontium manganite is ferromagnetic in large quantities.
When the RIKEN team presented their manganite thin film and explained its phase separation properties, Shen had what he wanted.
(PhysOrg. com) -- Using cutting-edge spectroscopy at atomic resolutions, researchers have discovered how to grow ultra-thin manganite films while retaining their magnetic properties.
To examine manganite samples grown by their collaborators in Japan, the scientists used a technique called electron energy loss spectroscopy, performed in a scanning transmission electron microscope.
