Magnetic contrast in phase-change materials doped with Fe impurities.
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.
