Stabilizing nanoparticles on surfaces, such as graphene, is a growing field of research. Thereby, iron particle stabilization on carbon materials is attractive and finds applications in charge-storage devices, catalysis, ...

We present Mossbauer studies of the influence of excess iron atoms on the properties of ironbased superconductor Fe1.09SeO.5TeO.5. Mossbauer spectra were collected in a temperature range from liquid helium up to room ...
