通过交流磁化率、磁化强度、电阻率和X射线衍射的测量，研究了SmMn2Ge2化合物的磁特性，并测定了p-T图。随着温度的降低，相变的顺序为：153K<；T<；341K出现铁磁性，106.5 K<；T<；153K反铁磁性趋于稳定，106.5 K以下出现再入铁磁性。观察到的磁相变与晶格参数的变化相对应。在反铁磁相中，磁场H-≈-6Koe诱导了向铁磁相的转变。还观察到了相变温度与压力的关系。
The magnetic characteristics of SmMn2Ge2compounds have been studied by measurements of ac susceptibility, magnetization, electrical resistivity and X-ray diffraction; thep-Tdiagram has also been determined. With decreasing temperature the phase transitions occur in the following sequence, ferromagnetism is observed in the temperature region of 153 K <T< 341 K, antiferromagnetism becomes stable for 106.5 K <T< 153 K and re-entrant ferromagnetism appears below 106.5 K. The observed magnetic phase transitions correspond with the change of the lattice parameters. In the antiferromagnetic phase the magnetic fieldH≈6 kOe induces the transition into the ferromagnetic phase. The pressure dependence of the phase transition temperatures was also observed.
