This work was supported by MCYT MAT 2002-2642 and CAM 07N/0032/2002 and Fundación Ramón Areces.Here we examine the ferromagnetic/superconducting proximity effect in half-metallic ferromagnetic La_(0.7)Ca_(0.3)MnO_(3) and high-T_(c) superconducting YBa_(2)Cu_(3)O_(7) artificial structures. We have found experimental evidence for the coupling between superconducting layers through ferromagnetic spacers in superlattices. This is consistent with a long-range proximity effect in half-metal ferromagnet/d-wave superconductor structures.engjournal articlehttp://dx.doi.org/10.1103/PhysRevB.69.224502http://journals.aps.org/open access537JunctionsSuperlatticesMultilayersTransportCoexistenceInterfaceLayers.ElectricidadElectrónica (Física)2202.03 Electricidad
