Ab initio simulation of the transition from the crystalline to the amorphous phase of a phase‐change material doped with Fe impurities . The structural and magnetic properties of both phases are studied and a link is provided between the magnetic contrast recently observed in these materials and the drastic change in local order which occurs during amorphization.
