Liu, Yaohua ; Cuéllar Jiménez, Fabián Andrés ; Sefrioui, Zouhair ; Freeland, J. W. ; Fitzsimmons, M. R. ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; te Velthuis, S. G. E. | American Physical Society | 2013-12-11We report a strong effect of interface-induced magnetization on the transport properties of magnetic tunnel junctions consisting of ferromagnetic manganite La_(0.7)Ca_(0.3)MnO_(3) and insulating cuprate PrBa_(2)Cu_(3)O_(7). Contrary to the typic[...]texto impreso
Peña, V. ; Sefrioui, Zouhair ; Arias Serna, Diego ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo ; Martínez, J. L. ; te Velthuis, S. G. E. ; Hoffmann, A. | American Physical Society | 2005-02-11We show magnetoresistance in excess of 1000% in trilayers containing highly spin-polarized La_(0.7)Ca_(0.3)MnO_(3) and high-T_(c) superconducting YBa_(2)Cu_(3)O_(7). This large magnetoresistance is reminiscent of the giant magnetoresistance (GMR[...]texto impreso

W. ; Zhou, H. ; Steadman, P. ; Bencok, P. ; León Yebra, Carlos ; Santamaría Sánchez-Barriga, Jacobo | American Institute of Physics | 2016-04In artificial multiferroics hybrids consisting of ferromagnetic La_(0.7)Sr_(0.3)MnO_(3) (LSMO) and ferroelectric BaTiO_(3) epitaxial layers, net Ti moments are found from polarized resonant soft x-ray reflectivity and absorption. The Ti dichroic[...]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
Nemes, Norbert Marcel ; Gárcia Hernández, M. ; te Velthuis, S. G. 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

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[...]
