Título: | Correlation between the electronic and atomic structure, transport properties, and oxygen vacancies on La0.7Ca0.3MnO 3 thin films |
Autor: | Rubio-Zuazo, J. CSIC ORCID; Onandia, L.; Ferrer, Pilar CSIC ORCID; Castro, Germán R. CSIC ORCID | Fecha de publicación: | 2014 | Editor: | American Institute of Physics | Citación: | Applied Physics Letters 104(2): 021604 (2014) | Resumen: | We present a study of the role of oxygen vacancies on the atomic and electronic structure and transport properties on a 20 nm thick La 0.7Ca0.3MnO3 film grown by the pulsed laser deposition method on a SrTiO3 (001) substrate. The results show that oxygen vacancies induce an atomic structure modification characterized by the movement of the La/Ca cations to the perovskite regular position, by the reduction of the MnO6 basal plane rotation, and by a cooperative tilting of the octahedra along the out-of-plane direction. The out-of-plane lattice parameter increases due to the reduction of the Mn valence upon oxygen vacancies creation. As a consequence, a shift of the Metal-to-Insulator transition to lower temperatures is found to occur. We discuss the influence of the competitive phenomena of manganese valence and Mn-O-Mn bond distortion on the transport properties of manganite thin films. © 2014 AIP Publishing LLC. | Versión del editor: | http://dx.doi.org/10.1063/1.4861385 | URI: | http://hdl.handle.net/10261/93929 | DOI: | 10.1063/1.4861385 | Identificadores: | doi: 10.1063/1.4861385 issn: 0003-6951 e-issn: 1077-3118 |
