Abstract
In this work we present a structural analysis of La 0.75 Sr 0.25 MnO 3 /LaNiO 3 (LSMO/LNO) superlattices, performed by X-ray diffraction spectroscopy and X-ray reflectivity. The samples were deposited by dc magnetron sputtering on single-crystalline (0 0 1) oriented SrTiO 3 . The strain relaxation and the roughness at the interfaces were estimated from the analysis of the X-ray patterns. The thickness of LSMO reference layers has been measured by means of low-angle X-ray reflectivity, finding a very good agreement with the nominal values. © 2007 Elsevier B.V. All rights reserved.
