Nemes, Norbert Marcel ; Visani, C. ; Sefrioui, Zouhair ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Iglesias, M. ; Mompean, F. ; Gárcia Hernández, M. | American Physical Society | 2010-01We examine the interplay between ferromagnetism and superconductivity in bilayer and trilayer heterostructures based on Co, YBa_(2)Cu_(3)O_(7-?) (YBCO), and La_(0.7)Ca_(0.3)MnO_(3) (LCMO) thin films grown on SrTiO_(3) substrates with typical thi[...]texto impreso
Bruno, Flavio Yair ; Grisolia, M. N. ; Visani, C. ; Valencia, S. ; Varela del Arco, María ; Aburdan, R. ; Tornos, J. ; Rivera Calzada, Alberto Carlos ; Ünal, A. A. ; Pennycook, S. J. ; Sefrioui, Zouhair ; León Yebra, Carlos ; Villegas, J. E. ; Santamaría Sánchez-Barriga, Jacobo ; Barthélémy, A. ; Bibes, M. | Nature Publishing Group | 2015-02-17At interfaces between complex oxides, electronic, orbital and magnetic reconstructions may produce states of matter absent from the materials involved, offering novel possibilities for electronic and spintronic devices. Here we show that magneti[...]texto impreso
Visani, C. ; Cuellar, F. ; Pérez Muñoz, Ana Mª ; Sefrioui, Zouhair ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Villegas, Javier E. | American Physical Society | 2015-07-31We experimentally study the superconducting proximity effect in high-temperature superconductor/halfmetallic ferromagnet YBa_(2)Cu_(3)O_(7)/La_(2/3)Ca_(1/3)MnO_(3) junctions, using conductance measurements. In particular, we investigate the magn[...]texto impreso
Nemes, Norbert Marcel ; Visani, C. ; León Yebra, Carlos ; Gárcia Hernández, M. ; Simón, F. ; Feher, T. ; te Velthuis, S. G. E. ; Hoffmann, A. ; Santamaría Sánchez-Barriga, Jacobo | American Institute of Physics | 2010-07-19We report a memory concept utilizing ferromagnet/superconductor/ferromagnet La_(0.7)Ca_(0.3)MnO_(3)/YBa_(2)Cu_(3)O_(7)/La_(0.7)Ca_(0.3)MnO_(3) thin film hybrid structures. The orientation of the magnetic field with respect to the ferromagnetic e[...]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
Peña, V. ; Visani, C. ; Garcia Barriocanal, Javier ; Arias Serna, Diego ; Sefrioui, Zouhair ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Almasán, Carmen A. | American Physical Society | 2006-03-27We report on the interplay between magnetism and superconductivity in La_(0.7)Ca_(0.3)MnO_(3)/YBa_(2)Cu_(3)O_(7) structures. We have grown heterostructures (bilayers and trilayers) with a constant thickness of the ferromagnetic layer of 40 unit [...]
