Abstract: In this work, we measure the internal magnetic field of a 100nm iron-doped palladium film by means of transversal field muon spin spectroscopy. The internal field and field inhomogeneity were measured in the bulk of the film from 3.5K to 100K and compared to measurements in a pure Pd film in order to investigate the effect of iron-doping. Furthermore, we compared these temperature sweeps to existing μSR measurements on bulk PdFe [1], in order to verify the quality of the film. Finally, we measured the internal field and field inhomogeneity at 3.5K as a function of muon implantation energy, in order to learn more about the spatial variation of the internal magnetic field. Ultimately, by doing this characterization, we hope that PdFe can serve as a testbed for other local magnetic field probe techniques.
