|Abstract:||The stability of the uniform alignment of lyotropic nematic liquid crystals doped with magnetic grains is theoretically analysed. The sample is assumed to be prepared in a uniformly magnetized state by means of an external magnetic field, which is switched off subsequently. We show that there is a critical concentration of magnetic grains above which the distorting effect of the magnetic interaction overcomes the stabilizing effect of the steric interactions among grains and micelles.|
