Structural and magnetic structures of Li3FeN2 at low temperature
Recently, we evidenced a magnetic ordering around 100K through Mössbauer measurements on Li3FeN2. Additional magnetic measurement reveal a broad and unclear antiferomagnetic-like transition. In addition, using several technics (NMR, XRD and Mössbauer), a cationic mixing has been proposed to complete the structural description proposed 25 years ago. The aim of this proposal is first, to confirm the cationic mixing and second, to investigate the nature of the magnetic ordering below the transition. To fulfill these objectives simultaneously, the use of neutron diffraction is best probe due to the magnetic scattering and the higher scattering factor of lithium compared to X-ray.
