Abstract
Lyotropic nematic mesophases doped with different concentrations of ferromagnetic grains are observed in a polarizing microscope. A minimum concentration of the grains is obtained above which a collective behavior of the nematic matrix is observed. The results are discussed in terms of the elastic continuum theory of liquid crystals.Keywords
