Biskup Zaja, Nevenko ; Das, S. ; González-Calbet, J. M. ; Bernhard, C. ; Varela del Arco, María | American Physical Society | 2015-05-26In this paper we present an atomic-resolution electron microscopy study of superlattices (SLs) where the colossal magnetoresistant manganite La_(0.67)Ca_(0.33)MnO_(3) (LCMO) and the high critical temperature superconducting cuprate La_(1.85)Sr_([...]texto impreso
Andrés Prada, R. de ; Gaina, R. ; Biskup Zaja, Nevenko ; Varela del Arco, María ; Stahn, J. ; Bernhard, C. | American Physical Society | 2019-09-16With dc magnetization and polarized neutron reflectometry we studied the ferromagnetic response of YBa_2Cu_3O_7/La_(2/3)Ca_(1/3)MnO_3 (YBCO/LCMO) multilayers that are grown with pulsed laser deposition. We found that whereas for certain growth c[...]texto impreso
León Yebra, Carlos ; Biskup Zaja, Nevenko ; Santamaría Sánchez-Barriga, Jacobo ; Alberca Carretero, Aurora ; Andrés, Amado de ; Gárcia Hernández, M. ; Munuera, C. ; Mompean, F.J. ; Nemes, Norbert Marcel | American Physical Society | 2012-10-24La0.7Ca0.3MnO3 optimally doped epitaxial films were grown on ferroelectric BaTiO3 substrates. Electronic transport (magnetoresistance and electroresistance) and magnetic properties showed important anomalies in the temperature interval between 6[...]texto impreso
Biskup Zaja, Nevenko ; Varela del Arco, María ; Mallet, B.P.P. ; Khmaladze, J. ; Marsik, P. ; Perret, E. ; Cerreta, A. ; Orlita, M. ; Bernhard, C. | American Physical Society | 2016-11-08We show that in Pr_(0.5)La_(0.2)Ca_(0.3)MnO_(3)/YBa_(2)Cu_(3)O_(7) (PLCMO/YBCO) multilayers the low temperature state of YBCO is very resistive and resembles that of a granular superconductor or a frustrated Josephson-junction network. Notably, [...]texto impreso
Mehta, V. V. ; Biskup Zaja, Nevenko ; Jenkins, C. ; Arenholz, E. ; Varela del Arco, María ; Suzuki, Y. | American Physical Society | 2015-04-23We demonstrate that a combination of electronic structure modification and oxygen vacancy ordering can stabilize a long-range ferromagnetic ground state in epitaxial LaCoO_(3) thin films. Highest saturation magnetization values are found in the [...]texto impreso
