Search for magnetic order in epsilon-iron at 20 GPa
In this proposal we ask for beamtime to collect high pressure neutron diffraction data of epsilon-iron at low temperatures. It is a continuation of experiment 5-31-1676 (June 2007) with a significantly improved experimental setup. Epsilon-iron is the high pressure phase of iron which is stable beyond 16 GPa (160 kbar). It has been speculated since decades that this phase might be magnetic. This would have important implications for the Earth Sciences (the Earth’s core is made of epsilon-iron), but also for fundamental solid state physics since epsilon-iron is superconducting below Tc=2 K.
