We have performed ferromagnetic resonance (FMR) studies of epitaxial V/Pd1-xFex (001) bilayers with a V thickness of the order of 40 nm and with a Pd1-xFex thickness in the range from 0.8 nm to 4.4 nm. For a bilayer with a Pd1-xFex thickness of 1.2 nm and x = 0.03 the FMR measurements revealed a decrease of the effective magnetization 4$\pi Meff$ of the ferromagnetic layer below the superconducting transition temperature of vanadium. As a possible explanation for this decrease we suggest a spatial modulation of the ferromagnetic order in the Pd1-xFex layer due to modifications of the indirect exchange interaction of magnetic ions via conduction electrons in the superconducting state. A comparison with a recent theoretical investigation supports this possibility.
