摘要：
We have studied the effect of pressure on the magnetic transition in CeRh2Ge2 and CeRu2Ge2 by electrical resistance measurements in the temperature range between 1.2 K and 300 K. Both samples show two magnetic transitions below 30 K. In CeRh2Ge2, the magnetic transition temperatures increase with increasing pressure. In the case of CeRu2Ge2, the upper magnetic transition temperature increases with pressure, whereas the lower one decreases with increasing pressure.
