Serrano, A. ; Llorca Hernando, O. ; Campo, A. del ; Rubio Marcos, F. ; Rodríguez de la Fuente, Óscar ; Fernandez, J. F. ; García, M. A. | Amer Inst Physics | 2018-10-07We present here a study on the modification of morphological and plasmonic properties of Ag thin films deposited on glass substrates upon annealing in air at different temperatures. Initially, Ag films are continuous and exhibit extended surface[...]texto impreso
Hemos estudiado los defectos superficiales en Au(001) 5x20 generados mediante dos diferentes técnicas experimentales: bombardeo iónico de baja energía y nanoindentación. Hemos analizado estos defectos con microscopía de efecto túnel (STM). Los e[...]texto impreso
Ortega Villafuerte, Yanicet ; Carmona Tejero, Noemi ; de Diego Otero, Nieves ; Rodríguez de la Fuente, Óscar | 2017-01El programa: Diseño e implementación de un laboratorio virtual para el estudio de "Defectos puntuales en cristales iónicos" enseña de forma interactiva las reglas de balance necesarias para escribir las ecuaciones de defectos en los cristales ió[...]texto impreso
López Sánchez, Jesús ; McIntosh, G. ; Osete López, María Luisa ; Campo García, A. del ; Villalain, J.J. ; Pérez García, Lucas ; Kovacheva, M. ; Rodríguez de la Fuente, Óscar | Amer Geophysical Union | 2017-07The identification of epsilon iron oxide (-Fe2O3) as the low Curie temperature high coercivity stable phase (HCSLT) carrying the remanence in heated archeological samples has been achieved in samples from two archeological sites that exhibited t[...]texto impreso
Ruiz Gómez, Sandra ; Serrano, A. ; Carabias,, I. ; Garc?a, M. A. ; Hernando Grande, Antonio ; Mascaraque Susunaga, Arantzazu ; Pérez García, Lucas ; González Barrio, Miguel Ángel ; Rodríguez de la Fuente, Óscar | American Institute of Physics | 2017-02-27We have used a low-energy ion bombardment to fabricate an epitaxial single-crystalline magnetite/hematite bilayer grown on Au(111). This non-conventional fabrication method involves the transformation of the upper layers of a single-crystalline [...]texto impreso
Martínez Pabón, María Beatriz ; Beltrán Finez, Juan Ignacio ; Sánchez Santolino, Gabriel ; Palacio, I. ; López Sánchez, Jesús ; Rubio Zuazo, J. ; Rojo Alaminos, Juan Manuel ; Ferrer, P. ; Mascaraque Susunaga, Arantzazu ; Muñoz, M. C. ; Varela del Arco, María ; Castro, G. R. ; Rodríguez de la Fuente, Óscar | Nature Publishing Group | 2015-02A plethora of technological applications justify why titanium dioxide is probably the most studied oxide, and an optimal exploitation of its properties quite frequently requires a controlled modification of the surface. Low-energy ion bombardmen[...]texto impreso
De la Venta, J. ; Fernandez Pinel, E. ; García, M. A. ; Crespo del Arco, Patricia ; Hernando Grande, Antonio ; Rodríguez de la Fuente, Óscar ; De Julián Fernández, C ; Fernández, A ; Penadés, S. | World Scientific Publ Co Pte Ltd | 2007-03-10We review here our recent results of experimental observation of room temperature magnetism in gold nanoparticles (NPs) and thin. films. Capping gold surfaces with certain organic molecules leads to the appearance of magnetism at room temperatur[...]texto impreso
Monti, Matteo ; Santos, Benito ; Mascaraque Susunaga, Arantzazu ; Rodríguez de la Fuente, Óscar ; Nino, Miguel Angel ; Mentes, Tevfik Onur ; Locatelli, Andrea ; McCarty, Kevin F. ; Marco, José F. ; Figuera, Juan de la | American Physical Society | 2012-01-11The oldest known magnetic material, magnetite, is of current interest for use in spintronics as a thin film. An open question is how thin can magnetite films be and still retain the robust ferrimagnetism required for many applications. We have g[...]texto impreso
Navarro, V. ; Rodríguez de la Fuente, Óscar ; Mascaraque Susunaga, Arantzazu ; Rojo Alaminos, Juan Manuel | American Physical Society | 2008-12Titanium dioxide rutile crystals have been nanoindented and studied by a combination of atomic force microscopy imaging and analysis of force vs penetration curves. In all the experiments, gold crystals have been used as a reference. A concept o[...]texto impreso

R. | Royal Society Chemical | 2019-06-09The purpose of this work is to fabricate self-assembled microstructures by the sol-gel method and study the morphological, structural and compositional dependence of epsilon-Fe_2O_3 nanoparticles embedded in silica when glycerol (GLY) and cetyl-[...]texto impreso
Navarro, V. ; Rodríguez de la Fuente, Óscar ; Mascaraque Susunaga, Arantzazu ; Rojo Alaminos, Juan Manuel | American Physical Society | 2008-03-14Gold vicinal surfaces (788), with a high density of steps, along with (111) flat surfaces taken as a reference, have been nanoindented and their resulting penetration curves and related defect structure comparatively analyzed by AFM and atomisti[...]texto impreso
Serrano, A. ; Gálvez Alonso, Fernando ; Rodríguez de la Fuente, Óscar ; García, M. A. | American Institute of Physics | 2013-03-21We present here a study of hard X-ray irradiation of soda-lime glasses performed in situ and in real time. For this purpose, we have used a Au thin film grown on glass and studied the excitation of its surface plasmon resonance (SPR) while irrad[...]
