Title

The antiferromagnetic structure of FeSe single crystal under pressure

Abstract

The magnetism of FeSe and its relation to superconductivity remain to be the main problems for iron based superconductivity. The microscopic model, magnetic ground state, nematicity, and pairing symmetry are among the main concerns. Very recently, experimental evidences indicate that antiferromagnetic transition occurs under pressure. This is important for the solution of the above concerned problems. Confirming the antiferromagnetic transition and determining the magnetic order by neutron scattering experiment are thus urgent. We propose to do neutron diffraction experiment on a high quality FeSe single crystal to illuminate its magnetism under pressure.
