  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$_7$ (YBCO) and ferromagnetic-metallic (FM-M)
La$_{0.67}$Ca$_{0.33}$MnO$_{3}$ (LCMO) or ferromagnetic-insulating (FM-I)
LaMnO$_{3+\delta}$ (LMO). We find that the MPE strongly depends on the
electronic state of the manganite layers, being pronounced for the FM-M LCMO
and almost absent for FM-I LMO. We also detail the change of the magnetic depth
profile due to the MPE and provide evidence for its intrinsic nature.
