摘要：

present the first experimental evidence of macroscopic one-dimensional patterns and forced wavelength selection in magnetic colloidal suspensions in an oscillating magnetic field. The resulting dramatic enhancement of the domain growth kinetics gives rise to concentration patterns composed of a main periodic structure and similar periodic substructures, which have a wave vector increasing with the excitation frequency, and decreasing with the suspension concentration.
