Bruno, F. Y. ; Tornos, J. ; Gutierrez del Olmo, M. ; Sánchez Santolino, G. ; Nemes, N.M. ; Gárcia Hernández, M. ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier ; Antorrena, G. ; Morellon, L. ; De Teresa, J. M. ; Clement, M. ; Iborra, E. ; León, C. ; Santamaría Sánchez-Barriga, Jacobo | American Physical Society | 2011-06-23Metallic surface layers are fabricated by doping (100) SrTiO_3 (STO) single crystals with oxygen vacancies generated by bombardment with Ar ions from an rf plasma source. The presence of oxygen vacancies is confirmed by cathodoluminescence and x[...]texto impreso
Bruno, F. Y. ; Garcia Barriocanal, Javier ; Torija, M. ; Rivera Calzada, Alberto Carlos ; Sefrioui, Zouhair ; Leighton, C. ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo | American Institute of Physics | 2008-02-25Electrical transport properties of heteroepitaxial p-n junctions made of La_(0.8)Sr_(0.2)CoO_(3) and SrTi_(0.99)Nb_(0.01)O_(3) were studied. Junctions display highly rectifying current-voltage characteristics over a wide temperature range (20–30[...]texto impreso
Pennycook, T. J. ; Oxley, M. P. ; Garcia Barriocanal, Javier ; Bruno, F. Y. ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Pantelides, S. T. ; Varela del Arco, María ; Pennycook, S. J. | E D P Sciences | 2011-06Colossal ionic conductivity was recently discovered in YSZ/SrTiO_(3) multilayers and was explained in terms of strain- and interface-enhanced disorder of the O sublattice. In the present paper we use a combination of scanning transmission electr[...]texto impreso
Nemes, Norbert Marcel ; Calderón, M. J. ; Beltrán Jiménez, José ; Bruno, F. Y. ; Garcia Barriocanal, Javier ; Sefrioui, Zouhair ; León Yebra, Carlos ; Gárcia Hernández, M. ; Muñoz, M. C. ; Brey, L. ; Santamaría Sánchez-Barriga, Jacobo | Wiley-V C H Verlag Gmbh | 2014-11-26The magnetoresistance of La0.7Sr0.3MnO3/SrTiO3La0.7Sr0.3MnO3/SrTiO3 superlattices with magnetic field rotating out-of-plane shows unexpected peaks for in-plane fields. Resistivity calculations with spin–orbit coupling reveal that orbital reconst[...]
