Abstract
Cation order, with a local structure related to γ-LiFeO$_2$, is observed in the nominally cation-disordered Li-excess rocksalt Li$_{1.25}$Nb$_{0.25}$Mn$_{0.5}$O$_2$ via X-ray diffraction, neutron pair distribution function analysis, magnetic susceptibility and NMR spectroscopy. The correlation length of ordering depends on synthesis conditions and has implications for the electrochemistry of these phases.
