Local hydrogen environments in Gd 1− x Fe x thin films amorphous alloys from effusion experiments

International audienceThin films of hydrogenated Gd,-XFeX (0.25 =%< 0.90) amorphous-alloys were prepared by reactive evaporation. Effusion experiments, showing several hydrogen release peaks, allowed us to describe the site distribution of hydrogen in these alloys. The different local environments correspond to tetrahedral sites and the stability of these sites increases with the number of rare-earth neighbors

Growth and characterization studies of Fe 4 N thin films prepared by ion beam assisted evaporation

International audienceThin films of iron nitrides have been prepared using an ion beam assisted evaporation method. X-ray diffraction and Mössbauer spectrometry show that the films generally consist in a mixture of Fe and Fe 4 N phases. For high source powers and temperatures higher than 300 °C it was possible to obtain the pure Fe 4 N phase
