Correlation of Magnetic and Superconducting Properties with the Strength of the Magnetic Proximity Effect in LaSrMnO/SrTiO/YBaCuO Heterostructures.

The effect of the stacking sequence on magnetic and superconducting properties in LaSrMnO (LSMO)/YBaCuO (YBCO) and LSMO/SrTiO/YBCO heterostructures, which consequently affected the magnetic proximity effect (MPE), was investigated using spin-polarized neutron reflectivity experiments. The results established the intrinsic nature of MPE and its correlation with stacking sequence-dependent magnetic and superconducting properties in these oxide heterostructure systems. We found an increase in the superconducting transition temperature () and magnetization for both of the heterostructures as compared to heterostructures with a reversed stacking order.
