Abstract

An antiferromagnet CeNiGe₃, which exhibits a quantum critical point at P_C ∼ 6 - 7 GPa, shows the superconductivity in wide pressure range of 1.7 - 9.3 GPa. In addition to the superconductivity around P_C, the sharp superconducting transition can be observed by both the resistivity and the susceptibility measurements at lower pressure region far apart from P_C, where 4f-localized picture seems to be still dominant. Such a superconductivity is a first example in the f-electron systems.
