the cotton-mouton coefficient was measured as a function of temperature and concentration in the isotropic phase of the ternary system potassium laurate (kl), 1-decanol, and d//2o. based on a micellar picture of mixed rods and disks, and in the context of an entropy model for hard cylinders, the data indicate the relative fraction of rods and disks as the kl concentration is adjusted in the vicinity of the isotropic - rod-like nematic - disk-like nematic coexistence point on the concentration-temperature phase diagram this data complements x-ray scattering results in the nematic phase (author abstract) 32 refs
