摘要	The microstructural characteristics of misfit dislocations at the interface between La0.9Sr0.1MnO3 films and vicinal SrTiO3 substrates have been studied by transmission electron microscopy. The misfit dislocations were determined to be edge type with Burgers vector a(100): Owing to the inclination of the substrate, the dislocation line along the miscut direction of the substrate is rotated. The deviation angle of the dislocation line away from the miscut direction of the substrate varies with the miscut angle. As a result, the dislocation arrays at the interface form a parallelogram dislocation network rather than an orthogonal network. A simple explanation of the misfit dislocation reaction with the step for the film on a vicinal substrate is proposed to interpret the rotation of the dislocation line along the miscut direction.
