Abstract
Using neutron reflectometry and resonant x-ray techniques we studied the magnetic proximity effect (MPE) in superlattices composed of superconducting and ferromagnetic-metallic or ferromagnetic-insulating . We find that the MPE strongly depends on the electronic state of the manganite layers, being pronounced for the ferromagnetic-metallic and almost absent for ferromagnetic-insulating . We also detail the change of the magnetic depth profile due to the MPE and provide evidence for its intrinsic nature.
