Order parameter in binary mixture by Monte Carlo simulation hybridized with mean field approximation

The order parameters of each component in a binary mixture consisting of su bstances exhibiting a nematic phase and an isotropic phase have been evalua ted by Monte Carlo simulation using the method of Vacatello and Iovino base d on the Flory-Ronca-Irvine mean field theory. An induction of ordering for an isotropic solute has been obtained in the nematic phase. The degree of induction is dependent not only on the parameters of the interactive orient ational potential but also on the anisotropy of the molecular shape of the isotropic solute.
