Sefrioui, Zouhair ; Arias, D. ; González Herrera, Elvira María ; León, C. ; Santamaría Sánchez-Barriga, Jacobo ; Vicent López, José Luis | American Physical Society | 2001-02-01Epitaxial YBa_2Cu_3O_7 thin films, grown by high-pressure de sputtering, an irradiated with He^(+) ions at 80 keV with doses between 10_(14) and 10_(15) cm^(-2). Irradiation reduces the critical temperature but it does not modify the carrier con[...]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)] .[...]
