摘要
The energy loss near edge structure (ELNES) of the O-K, Ti-L-23 and Mn-L-23 edges have been recorded in hexagonal Ba(3)Ti(2)NlnO(9) with an energy resolution of 0.10-0.20eV using a monochromator on a commercial transmission electron microscope (TEM) and compared with a tetragonal BaTiO3 reference sample. The formal valency and symmetry of Mn have been determined using atomic multiplets calculations and its effect on the electronic structure of BaTiO3 has been interpreted through a molecular-orbital model.
