Abstract
Here we report on a feasibility study aiming to explore the potential of Polarized Neutron Reflectometry (PNR) for detecting the inverse proximity effect in a single superconducting/ferromagnetic bilayer. Experiments, conducted on the V(40 nm)/Fe(1 nm) S/F bilayer, have shown that experimental spin asymmetry measured at T=0.5TC is shifted towards higher Q values compared to the curve measured at T=1.5TC. Such a shift can be described by the appearance in superconducting vanadium of magnetic sub-layer with thickness of 7 nm and magnetization of +0.8 kG. |
