In previous work, we investigated the formation of biaxial nematic phases in a model system consisting of a binary mixture of uniaxial molecules. The model potential was set up such that like molecules of each mixture component prefer a parallel alignment whereas two unlike molecules align preferentially in a T-shaped configuration. By tuning the potential parameters, we avoid a decomposition of the mixture which has hampered earlier studies because of its competition with the formation of an ordered biaxial phase. In this work we study the local orientational structure in a binary, decomposed mixture of uniaxial liquid crystals, using the same model as for the mixed phases, but lowering the interaction potential between particles of different kinds.
