Gálvez Alonso, Fernando ; Monton, C. ; Serrano, A., A. ; Valmianski, I. ; De la Venta, J. ; Schuller, Ivan K. ; García, M. A. | Elsevier Science S A | 2012-09We study the effect of photodiode angular response on the measurement of surface plasmon resonance (SPR) in metallic thin films using the Kretschmann-Raether configuration. The photodiode signal depends not only on the light intensity but also o[...]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
Serrano, A. ; Monton, C. ; Valmianski, I. ; Gálvez Alonso, Fernando ; Cortajarena, Aitziber L. ; De la Venta, J. ; Schuller, Ivan K. ; García, M. A. | American Institute of Physics | 2014-03-14We present a Surface Plasmon Resonance spectroscopy study of Co-Phthalocyanine (CoPc) thin films grown on Au layers at different substrate temperatures. We demonstrate that for quantitative analysis, fitting of the resonance angle alone is insuf[...]texto impreso
Garcia March, M. A. ; Jimenez Villacorta, F. ; Quesada, A. ; De la Venta, J. ; Carmona Tejero, Noemi ; Lorite, I. ; LLopis, J. ; Fernandez, J. F. | American Institute of Physics | 2010-01-15We recently reported the observation of room temperature ferromagnetism in mixtures of ZnO and Co_3O_4 despite the diamagnetic and antiferromagnetic character of these oxides, respectively. Here, we present a detailed study on the electronic str[...]
