Abstract

A surprising observation of order induced in the disordered (isotropic) phase of the lyotropic KL/DeOH/water mixture was experimentally verified using a pulsed laser beam. This effect is reported here for the first time, to the best of our knowledge. We present a theoretical approach based on a diffusion‐like equation that is in good agreement with the experimental results.
