Elucidating Magnetic Order in a Novel Iron Oxalate KFe(C2O4)F by Powder Neutron Diffraction

Abstract: The increasing demand for portable energy means that the search for new electrode materials for rechargeable solid-state batteries is a key challenge in materials science. Lithium-ion batteries are used in a variety of portable devices, but the limited supply of lithium and its rising cost have encouraged a shift in interest towards more sustainable sodium-ion battery alternatives. Recently, we have explored the synthesis and properties of various Fe2+-based oxalate systems related to phases suitable for use in lithium- and sodium-ion batteries. In doing so, we have uncovered a number of interesting new analogues, including KFe(C2O4)F. Our initial characterisation of KFe(C2O4)F suggests that this system undergoes a magnetic ordering transition at 20 K. Here, we propose to explore the nature of the magnetically ordered state via variable temperature powder neutron diffraction.
