中文摘要	Microstructures in the thin film of La0.8Sr0.2MnO3 grown on (100) SrTiO3 by laser molecular beam epitaxy were characterized by transmission electron microscopy. Highly dense and dimensionally uniform nano-agglomerates were found embedded in thin film of La0.8Sr0.2MnO3. High-angle angular dark-field imaging, elemental mapping, and compositional analysis revealed that the nano-agglomerates are rich in manganese and poor in lanthanum. The ratio of Mn/La in the nano-agglomerates fluctuates. A salient feature of this compositional fluctuation within the nanoscale is the formation of cubic MnO phase, which appears as the core of the nano-agglomerates. The La0.8Sr0.2MnO3 film is domain-oriented and two domains were identified on the basis of orthorhombic lattice. The orientation relationships between La0.8Sr0.2MnO3 domains and MnO were determined as [010](LSMO,1)//[001](MnO) and (100)(LSMO,1)// (110)(MnO); [101](LSMO,2)//[001](MnO) and (010)(LSMO,2)//(100)(MnO). The domain structures and compositional inhomogeneities within nanoscale result in a textured inicrostructure, which is one of the most important parameters for tuning electronic properties in colossal magnetoresistance oxides.
