摘要：

From resistivity measurements of single crystalline CeAl3 and CeCu2Ge2 we discuss the pressure-induced disappearance of magnetic ordering at P-c approximate to 1 and 70 kbar, respectively. The simultaneous emergence of superconductivity in CeCu2Ge2 near P-c is also addressed in reference to the case of CeCu2Si2. Due to pressure inhomogeneity in the high pressure transmitting medium (steatite) we still cannot conclude about the microscopic coexistence of superconductivity and magnetic ordering in CeCu2Ge2.
