摘要：

The magnetic properties and the magnetoresistance of polycrystalline SmMn2Ge2 were studied. Magnetic phase transitions associated with different types of magnetic ordering were observed near 100 K and 150 K. Between these two temperatures the zero-field magnetization vanishes, but there is a field-induced transition to a basically ferromagnetic state. Measurements made at 125 K suggest that this transition is accompanied by a large magneto-resistance effect (DELTAR/R = 16%).
