Pérez de Lara, David ; Castaño, F. J. ; Ng, B. G. ; Körner, H. S. ; Dumas, R. K. ; González Herrera, Elvira María ; Liu, Kai ; Ross,, C. A. ; Schuller, Ivan K. ; Vicent López, José Luis | American Institute of Physics | 2011-10-31Strong superconducting pinning effects are observed from magnetic landscapes produced by arrays of circular rings with varying magnetic remanent states. The collective and the background pinning of superconducting Nb films is strongly enhanced b[...]texto impreso
Niu, Yue ; Frisenda, Riccardo ; Svatek, Simon A. ; Orfila, Gloria ; Gallego, Fernando ; Gant, Patricia ; Agrait, Nicolás ; León Yebra, Carlos ; Rivera Calzada, Alberto Carlos ; Pérez de Lara, David ; Santamaría Sánchez-Barriga, Jacobo ; Castellanos Gómez, Andrés | IOP Publishing Ltd. | 2017-09The fabrication of artificial materials by stacking of individual two-dimensional (2D) materials is amongst one of the most promising research avenues in the field of 2D materials. Moreover, this strategy to fabricate new man-made materials can [...]texto impreso
Pérez de Lara, David ; Castaño, F. J. ; Ng,, B. G. ; Körner, H. S. ; Dumas, R. K. ; González Herrera, Elvira María ; Liu, Kai ; Ross,, C. A. ; Schuller, Ivan K. ; Vicent López, José Luis | American Physical Society | 2009-12A ratchet effect (the rectification of an ac injected current) which is purely magnetic in origin has been observed in a superconducting-magnetic nanostructure hybrid. The hybrid consists of a superconducting Nb film in contact with an array of [...]texto impreso
Pérez de Lara, David ; Erekhinsky, M. ; González Herrera, Elvira María ; Rosen, Y. J. ; Schuller, Ivan K. ; Vicent López, José Luis | American Physical Society | 2011-05-09Triangular arrays of Ni nanotriangles embedded in superconducting Nb films exhibit unexpected dynamical vortex effects. Collective pinning with a vortex-lattice configuration different from the expected fundamental triangular "Abrikosov state" i[...]
