Abstract
We have investigated high field magnetization on single-crystalline CeFe 2 Ge 2 which is classified as a heavy fermion with a non-magnetic ground state. A clear metamagnetic anomaly, which resembles those reported in CeRu 2 Si 2 , was observed around 300 kOe for the field along the c -axis. The T 3/2 dependence of the electrical resistivity in a wide temperature range from around 15 K down to 2 K, followed by T 2 dependence at lower temperatures, is apparently similar to that in CeNi 2 Ge 2 which is close to a quantum critical point.Keywords
