Prieto, P. ; Vivas, P. ; Campillo, G. ; Baca, E. ; Castro, L. F. ; Varela del Arco, María ; Ballesteros, C. ; Villegas, J. E. ; Arias Serna, Diego ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo | American Institute of Physics | 2001-06-15We report on the magnetic and superconducting properties of La_(0.7)Ca_(0.3)MnO_(3)/YBa_(2)Cu_(3)O_(7) (LCMO/YBCO) superlattices. For a constant LCMO layer thickness of 6 unit cells (u.c.), resistance and susceptibility measurements show superco[...]texto impreso
Lucía Mulas, María Luisa ; Sánchez Quesada, Francisco ; Santamaría Sánchez-Barriga, Jacobo ; Sefrioui, Zouhair ; Varela del Arco, María ; Arias Serna, Diego ; Loos, G. ; Navacerrada, M.A. | American Institute of Physics | 1998-12-07We have studied the effect of He+ irradiation on the electrical resistivity and Curie temperature of ferromagnetic SrRuO3 thin films. An evolution from metallic to insulating behavior is observed when He+ ion fluence is increased, suggesting a m[...]texto impreso

E. ; Hoffmann, A. ; Visani, C. ; Garcia Barriocanal, Javier ; Peña, V. ; Arias Serna, Diego ; Sefrioui, Zouhair ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo | American Physical Society | 2008-09We studied ferromagnet/superconductor/ferromagnet trilayers based on La_(0.7)Ca_(0.3)MnO_(3) manganite and YBa_(2)Cu_(3)O_(7??) (YBCO) high-T_(c) cuprate with magnetoresistance and magnetization measurements. We find an inverse superconducting s[...]texto impreso
Arias Serna, Diego ; Sefrioui, Zouhair ; Loos, G. ; Agulló-Rueda, F. ; Garcia Barriocanal, Javier ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo | American Physical Society | 2003-09-01We report on the effect of oxygen disorder in the CuO chains on the superconducting properties of oxygen depleted YBa_(2)Cu_(3)O_(x)(YBCO). While moderate disorder, induced thermally, depresses the critical temperature as a result of a reduced c[...]texto impreso
López de la Torre, M. A. ; Peña, V. ; Sefrioui, Zouhair ; Arias Serna, Diego ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Martínez, J. L. | American Physical Society | 2006-02-14We report the observation of a paramagnetic contribution to the field cooled magnetization that develops below the superconducting transition temperature T_(c) in measurements performed on YBa_(2)Cu_(3)O_(7)/La_(0.7)Ca_(0.3)MnO_(3) superlattices[...]texto impreso

L. ; te Velthuis, S. G. E. ; Hoffmann, A. | American Physical Society | 2007-02We report on large magnetoresistance in ferromagnet/superconductor/ferromagnet trilayer structures made of La_(0.7)Ca_(0.3)MnO_(3) and YBa_(2)Cu_(3)O_(7). We find that the shape and height of the magnetoresistance peaks are not modified when the[...]texto impreso

We have grown heterostructures (bilayers and trilayers) with a constant thickness of the ferromagnetic layer of 40 unit [...]texto impreso
Sefrioui, Zouhair ; Arias Serna, Diego ; González Herrera, Elvira María ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Vicent López, José Luis | American Physical Society | 2001-01-18Epitaxial YBa_(2)Cu_(3)O_(7) thin films, grown by high-pressure dc sputtering, are 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 carr[...]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.
