Abstract
The temperature and field dependence of susceptibility for α, β and γ phases of LiFeO2 have been measured. Transition temperatures are observed at 42°K for α and β and at 295°K for γ phases, which are identified as Néel temperatures. The temperature dependence of susceptibility curves show departures from Curie-Weiss behaviour for each phase. This is explained in terms of short-range ordering of Fe and Li ions in the cases of α and β. The γ structure is ordered and the Weiss molecular field theory is applied to it, using a 16-sublattice model. The results of the calculation illustrate the limitations of the Weiss model in this structure.
