Using a superconducting solenoid attainable up to 40 kG, me;tsurements have beenmade of the transverse magnetoresistance and Hall voltages in thc Mn-doped (0.88 and2.2 at. '%) SnTe crystals at liquid helium temperatures. The m?tgnetic impurity spinsalign ferromagnetically below certain temperature T.., around which the magnetoresis-lance becomes negative. The observed Hall effect consists of the utormal temperature-independent component 7<. and the extraordinary component i<. which appears onlybelow T... A graphically estimated saturation magnetization obccys approximately theBloch T"' law, which clearly SIIOWS the presence of ficrromagmelism in this Mn-dopeddegenerate semiconductor
