Using neutron reflectometry and resonant x-ray techniques we studied the magnetic proximity effect (MPE) in superlattices composed of superconducting YBa(2)Cu(3)O(7) and ferromagnetic-metallic La(0.67)Ca(0.33)MnO(3) or ferromagnetic-insulating LaMnO(3+delta). We find that the MPE strongly depends on the electronic state of the manganite layers, being pronounced for the ferromagnetic-metallic La(0.67)Ca(0.33)MnO(3) and almost absent for ferromagnetic-insulating LaMnO(3+delta). We also detail the change of the magnetic depth profile due to the MPE and provide evidence for its intrinsic nature. © 2012, American Physical Society
