Description

We report the results of resonant X-ray scattering (RXS) measurement of superlattices which consist of La0.45Sr0.55MnO3 and La0.60Sr0.40MnO3 multilayers. An interference technique made it possible to observe RXS reflections from ferro-type orbital ordering in the superlattices. RXS can reveal the local circumstances around specific atoms in materials regulated atomically. In this experiment, we observed that the superlattice is actually composed of two kinds of layers with different lattice distortion states, presenting 'orbital superlattices', in which layers with different orbital states are stacked alternately in an atomic scale.
