Resistivity measurements of frozen mixtures of Xe and Fe versus concentration and temperature exhibit various conduction regions including a nonconducting-to-conducting transition at ∼30 at.% Fe. Mössbauer-effect measurements reveal no changes in isomer shift or hyperfine magnetic field with concentration above ∼14 at.% Fe. However, the change in shape of the Mössbauer spectra suggests that a transition from a paramagnetic relaxing phase to a magnetically ordered phase occurs at ∼30 at.% Fe.
