A magnetorheological (MR) fluid including magnetically soft particles suspended in a carrier solvent is disclosed. The MR fluid also includes additive particles of smaller size than the magnetically soft particles and a bridging polymer. The additive particles and polymer form a gel-like material which provides a blanket or coating around the magnetically soft particles. The MR fluids possess improved stability and redispersibility, as well as favorable mechanical properties.

[ What is claimed is:] [1.] A magnetorheological fluid comprising:(a) a solvent; and(b) magnetically soft particles at least partially covered with additive particles bridged with a polymer suspended in the solvent, wherein the polymer comprises linear or branched molecules which are long enough to bridge the distance between the additive particles in the magnetorheological fluid to thereby form an interconnected blanket of the polymer and additive particles.
