González Herrera, Elvira María ; Anguita, J. V. ; Villegas, J. E. ; Vicent López, José Luis | Elsevier Science BV | 2003-05Ordered arrays of submicrometric Ni lines have been fabricated in sputtered Nb films. Magnetotransport R(H) and (I, V) curves were measured close to the critical temperature using a cross-shape bridge that allows us to apply current in two direc[...]texto impreso
Villegas, J. E. ; González Herrera, Elvira María ; Sefrioui, Z. ; Santamaría Sánchez-Barriga, Jacobo ; Vicent López, José Luis | American Physical Society | 2005-11Magnetotransport properties have been used to investigate vortex phases in Nb films with periodic arrays of magnetic pinning centers. This kind of samples show a continuous glass transition similar to that observed in Nb plain films, but the per[...]texto impreso
Gómez, A. ; Valle Granda, Javier del ; González Herrera, Elvira María ; Chiliotte, C. E. ; Carreira, S. J. ; Bekeris, V. ; Prieto, J. L. ; Schuller, Ivan K. ; Vicent López, José Luis | IOP publishing ltd | 2014Hybrid magnetic arrays embedded in superconducting films are ideal systems to study the competition between different physical (such as the coherence length) and structural length scales such as are available in artificially produced structures.[...]texto impreso
Pérez de Lara, D. ; Alija, A. ; González Herrera, Elvira María ; Vélez, M. ; Martín, J. I. ; Vicent López, José Luis | American Physical Society | 2010-11-03Arrays of Ni nanodots embedded in Nb superconducting films have been fabricated by sputtering and electron-beam lithography techniques. The arrays are periodic triangular lattices of circular Ni dots arranged in a kagomélike pattern with broken [...]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[...]texto impreso
Sefrioui, Zouhair ; Arias Serna, Diego ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; González Herrera, Elvira María ; Vicent López, José Luis ; Prieto, P. | American Physical Society | 2004-08-09We investigate the zero-magnetic-field dynamic scaling in Bi_(2)Sr_(2)CaCu_(2)O_(8) thin films from nonlinear currentvoltage sI-Vd characteristics and by using the concavity criterion recently proposed by Strachan et al. [Phys. Rev. Lett. 87, 06[...]texto impreso
Sefrioui, Z. ; Arias, D. ; León, C. ; Santamaría Sánchez-Barriga, Jacobo ; González Herrera, Elvira María ; Vicent López, José Luis | American Physical Society | 2004-08We investigate the zero-magnetic-field dynamic scaling in Bi_2Sr_2CaCu_2O_8 thin films from nonlinear current-voltage (I-V) characteristics and by using the concavity criterion recently proposed by Strachan [Phys. Rev. Lett. 87, 067007 (2001)] .[...]
