Abstract

New accurate diamagnetic measurements of the order parameter, just below the nematic-isotropic transition temperature Tc, are given for two nematic liquid crystals. The variations with temperature of the order parameter are described well by theory based on the Landau expansion of the free energy. The subsequent determinations of TcT* and the latent heat are in good agreement with values obtained by an independent way.
