Abstract

The high-field magnetization and the temperature variation of magnetic susceptibility in Ce_1-xLa_xFe₂Ge₂ were examined to better understand the metamagnetic anomaly in CeFe₂Ge₂. A metamagnetic anomaly from a non-magnetic ground state on single crystalline CeFe₂Ge₂ and Ce_1-xLa_xFe₂Ge₂ was observed at H = 300 kOe. For Ce_1-xLa_xFe₂Ge₂, the metamagnetic anomaly smeared out for x≥0.1. However, no magnetic order or non-Fermi-liquid behavior was observed for x≤0.2, in contrast with the case of Ce_1-xLa_xRu₂Si₂ in which the magnetic instability was reported for x = 0.08.
