Manganite crystal

According to the microwave-assisted method, high-purity metallic oxides Mn3O4 and NiO are used, are pressed and sintered together and are heated by using a microwave oven at certain temperature, the temperature is kept for a period of time The signature of correlated electron materials (CEMs) is the coupling between spin, charge, orbital and lattice resulting in exotic functionality. This complexity is directly responsible for their tunability. We demonstrate here that the broken symmetry, through cubic to orthorhombic distortion in the lattice structure in a prototype manganite single crystal, La0.69Ca0.31MnO3, leads to an Manganite crystal overlaid with displacements (arrows) at each atomic column. Two striped structures (blue/yellow and green/red), at 90-degree angles from each other, compete for nanoscale territory.

The 'flat top' terminations of the large crystals are sharp and well defined. A classic Manganite that displays well.

The color is dark steel-grey to iron-black, and the luster brilliant and submetallic.

Manganite was a valuable manganese ore when it was found in plentiful deposits. Now its rarity has relegated it to the standing of a minor ore dispite its high manganese content. Crystals are the chief indicator for identification.

Multiple twinning is common.
