摘要：
We report magnetic susceptibility, electrical resistivity and specific heat measurements on single-crystal specimens of Ce2Cu8Al9 with the rhombohedral Th2Zn17-type crystal structure. The low-temperature specific heat has revealed heavy-fermion behavior, i.e., C/T attaining an extremely large value of about 2.7 J/K2 mol-Ce around 0.7 K, which is greatly reduced by an applied magnetic field, namely, down to less than half of the zero-field value for H = 5.2 T. It is indicated from the present experiments that Ce2Cu8Al9 is a new heavy-fermion material of T(K) is similar to 3 K.
