报告了金属间化合物 CePd2Al3、CeNi2Al3、CePdSb3、CeNiGa3（两种形式）、Ce2Ni3Si5 和 CeNi2Sb2 的磁化率、电阻率和低温比热测量。 CeNi2Sb2 的载流子质量增强最大，其比热系数 γ 约为 400 mJ/mol Ce K2。在 CeNi2Al3 和 Ce2Ni3Si5 中，没有观察到局部 Ce 矩。电阻率测量表明，没有任何化合物在高于 50 mK 时变得超导。
The magnetic susceptibility, resistivity and low-temperature specific heat measurements are reported for the intermetallic compounds CePd2Al3, CeNi2Al3, CePdSb3, CeNiGa3 (two forms), Ce2Ni3Si5 and CeNi2Sb2. The largest carrier mass enhancement is found for CeNi2Sb2 with a specific heat coefficient gamma of approximately 400 mJ/mol Ce K2. In CeNi2Al3 and Ce2Ni3Si5 no local Ce moments are observed. Resistivity measurements reveal that no compound becomes superconducting above 50 mK.
