To continue with our study on the interaction between superconducting (SC) and ferromagnetic (FM) order parameters we propose to study, by means of Polarized Neutron Reflectometry, the magnetic depth profile of YBa2Cu3O7 (YBCO) / LaMnO3+x (LMO) superlattices as a function of temperature. Since the oxygen content of LMO can stabilize FM metallic and FM insulating phases, we plan to study the possible occurrence of a superconductivity induced change in the magnetic profile inside the LMO layers, as has been observed for us previously in YBCO/La2/3Ca1/3MnO3 superlattices, and determine how this effect is affected by the transport properties of the FM layers. In additon, we plan to study the correlation between the transport properties of the ferromagnetic layer and the existence of a region next to the interface with suppressed ferromagnetic order.
