Abstract
Epitaxial V/Pd1−x Fe x (001) bilayers with a V thickness of the order of 40 nm and with a Pd1−x Fe x thickness in the range from 0.8 nm to 4.4 nm were prepared by molecular beam epitaxy techniques. The Curie temperature of the Pd1−x Fe x layers varies between 90 and 250 K. For a bilayer with a Pd1−x Fe x thickness of 1.2 nm the ferromagnetic resonance measurements revealed a decrease of the effective magnetization 4πM eff of the ferromagnetic layer below the superconducting transition temperature of V. As a possible explanation for this decrease we suggest a spatial modulation of the ferromagnetic order in the Pd1−x Fe x 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.
