Magnetic structure of hexagonally stabilized (Lu,In)FeO₃

Hexagonal LuFeO₃ has recently attracted considerable attention as promising candidates for room-temperature multiferroics, in which ferroelectricity and magnetism coexist in a single phase. However, most studies have been performed in a thin film form due to the instability of the bulk hexagonal LuFeO₃. Herein, we report that in LuFeO₃ a single hexagonal phase can be stabilized in both polycrystalline and single-crystalline bulk form with a wide range of Indium substitution in Lutetium site. Neutron diffraction results on magnetic spin structures and crystal structures of the Indium substituted LuFeO₃ will be discussed.
