Abstract
We have studied the temperature dependence of the electrical resistivi ty, the magnetic susceptibility and the high-field magnetization of Ce Ni2Ge2. Quadratic temperature dependence of the resistivity is observe d below 0.7 K. The susceptibility exhibits a broad maximum at 28 K. Ma gnetization shows metamagnetic behavior at H-M similar to 42 T as in C eRu2Si2. These results indicate that CeNi2Ge2 is a new heavy-fermion c ompound showing the metamagnetic behavior in the nonmagnetic ground st ate.
