A magnetorheological suspension (MRS) obtained by thermal decomposition of Fe2(CO)9 in mineral oil with stearic acid was prepared. The mean diameter of the microparticles was 2.10 μm at a standard deviation of 0.40 μm. For volume fractions of 0.06 and 0.30, the MRS is conductive only for alternative magnetic fields with a minimal effective intensity of 60 kA/m. The experimental results are discussed.
