Non-collinear two-dimensional triangular antiferromagnets (2D TLAF) are currently an area of much active research due to their unique magnetic properties, which lead to non-trivial quantum effects that experimentally manifest themselves in the spin excitation spectra. Recent examples of such insulating 2D TLAF include (Y,Lu)MnO₃ and CuCrO₂. LuFeO₃ is a recently discovered multiferroic material, which is isostructural to LuMnO₃and contains one more electron in the e_g manifold. Characterization of the AFM ground state (T_N= 155 K) in LuFeO₃ thin films with magnetometry and neutron diffraction has been previously reported. We present the first report of the spin dynamics in a bulk single crystal of (Lu_0.6Sc_0.4)FeO₃ measured via time-of-flight inelastic neutron scattering, and compare and contrast these results with those found in LuMnO₃.
