Abstract

We report on the stability of the V magnetic moment within Fe/V superlattices upon H-uptake. At the Fe/V interface V atoms acquire a magnetic moment, antiparallel aligned to the Fe moments. Upon hydrogen loading the saturation magnetization was found to increase. We utilized element specific X-ray resonant magnetic scattering to address the response of the induced V moments. An epitaxial [Fe(5ML)/V (16ML)]×30 superlattice was employed. The soft x-ray measurements were carried out using the ALICE diffractometer at BESSY II in Berlin, Germany. The data clearly show the stability of the V moment upon H-loading. No change of the magnetic asymmetry at the V edge could be recognized. Our measurements confirm ab-initio calculations predicting a stable V moment and an increase of the Fe moment in H loaded Fe/V superlattices.
