Abstract
An elastic description of media characterized by interparticle interac tions having a short and a long range part is presented. The bulk equi librium equations, whose solutions correspond to the actual deformed s tates, are obtained. This formalism is used to describe lyotropic nema tic liquid crystals doped with magnetic grains. For these materials we predict a new type of orientational instability, due to the magnetost atic interaction among the magnetic grains. (C) 1998 Elsevier Science B.V.
