概要
- 論文の詳細を見る
We report magnetic susceptibility, electrical resistivity and specific heat measurements on single-crystal specimens of Ce_2Cu_8Al_9 with the rhombohedral Th_2Zn_<17>-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/K^2 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 Ce_2Cu_8Al_9 is a new heavy-fermion material of T_K〜3 K.
