Propagation characteristics of dust acoustic solitons are studied in a magnetized dusty plasma consisting of ions, electrons and negatively charged dust grains. It is found that rarefactive solitons (solitons associated with negative potentials) are possible in such a plasma. The effects on the soliton characteristics of magnetic field strength, wave propagation angle, and densities and temperatures of the plasma particles are analysed.
