我们测量了反铁磁体CeIrSi_3(Néel温度TN=5.0K)和CeIrGe_3(TN_1 =8.7K,TN_2 =4.7K)在压力下的电阻率。CeIrSi_3在1.8GPa ~ 3.5GPa范围内具有超导电性,其超导转变温度为Tsc=1.6K,临界压力Pc = 2.5GPa,Néel温度为零。另一方面,CeIrGe 3的反铁磁有序在8 GPa下是稳定的。
We measured the electrical resistivity in antiferromagnets CeIrSi3(a Néel temperature TN=5.0K) and CeIrGe3(TN1=8.7K, TN2=4.7K) under pressure. In CeIrSi3, superconductivity was found in a wide pressure region from 1.8GPa to about 3.5GPa, where the superconducting transition temperature is Tsc=1.6K at a critical pressure Pc≃2.5GPa at which the Néel temperature becomes zero. On the other hand, the antiferromagnetic ordering of CeIrGe3is stable up to 8GPa.
