Resumen:
In this work we present a structural analysis of La0.75Sr0.25MnO3/LaNiO3
(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 SrTiO3.
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.
