We demonstrate a new route to enhance the magnetorheological effect using bimodal
suspensions in the single-multidomain limit. Experimental results are satisfactorily compared to
3D finite element method simulations. The physical reason behind this enhancement is the
coating of the larger particles by the smaller ones due to the remnant magnetization of the latter.
