Elastic and orbital effects on thickness-dependent properties of manganite thin films
/ Authors
/ Abstract
Mn-nuclear magnetic resonance data and x-ray photoemission spectroscopy, signal that the depression of themagnetic properties of the more strained 001 LCMO films is not caused by an elastic deformation of theperovskite lattice but rather due to the electronic and chemical phase separation caused by the substrate-induced strain. On the contrary, the thickness dependence of the magnetic properties of the less strained 110 LCMO films are simply described by the elastic deformation of the manganite lattice. We will argue thatthe different behavior of 001 and 110 LCMO films is a consequence of the dissimilar electronic structure ofthese interfaces.DOI: 10.1103/PhysRevB.76.224415 PACS number s : 75.47.Lx, 75.70. i
