Surface Nanostructures in Manganite Films

Ultrathin manganite films are widely used as active electrodes in organic spintronic devices. In this study, a scanning tunnelling microscopy (STM) investigation with atomic resolution revealed previously unknown surface features consisting of small non-stoichiometric islands. Based upon this evidence, a new mechanism for the growth of these complex materials is proposed. It is suggested that t...

Colossal magnetoresistive manganite thin films

Mixed-valence perovskite manganites (Re 1−x A x MnO 3 where Re=rare earth, A=alkaline earth) provide a unique opportunity to study the relationships between the structure and the magnetotransport properties due to an interplay among charge carriers, magnetic coupling, orbital ordering and structural distortion. This makes these compounds very exciting from both the basic research and from the t...

Influence of strain on the atomic and electronic structure of manganite films

A study of the long-range, local and electronic structure of Nd0.5Sr0.5MnO3 films of varying thickness between 500 and 2000 Å has been performed. Local structure measurements at the Sr K-edge reveal a reduction of the Mn–O–Mn bond angles in films below 1000 Å. Spin-polarized measurements reveal splitting of the Mn 3d eg state in the strained region of the films and are consistent with a two-lay...
