摘要：

We investigated two intermetallic compounds, CeZn11 and UZn12, for heavy-electron behavior and found that the coefficient of low-temperature specific heat is about 850-900 mJ/(mol K2) for UZn12. The compound CeZn11, which has a relatively small gamma value of 43.2 mJ/(mol K2), exhibited an antiferromagnetic long-range order at 2.0 K evidenced by a large peak of the specific heat and a broad maximum in the susceptibility, while UZn12 exhibited neither superconducting nor magnetic phase transition down to 0.4 K.
