| 中文摘要 | In this paper, the experimental results of the low-temperature resistance between 0.1K to 250K and specific heat between 5K to 70K of heavy fermion compounds CeCu6-xNix (x = 0.0,0.05,0.1,0.15,0.2) are reported. The doping effect of the Ni content on the low-temperature properties of CeCu6 is studied. The temperatures of resistance maximuas of the samples reduce dramatically with the increase of the doping content x. This indicates the enhancement of magnetic moment of minor Ce ions that are neighboring Ni atom and the decrease of the coherent scattering between the whole Ce ion lattice and the conduction electrons. The low-temperature electronic specific heat coefficient gamma(C-E/T, where C-E is the electronic specific heat) is nearly a constant at low temperatures, but it apparently increases below 8K due to the increase of its effective mass. However, the temperature at which gamma begins to increase is not sensitive to the content of Ni, indicating that the status of most cerium ions are not affected. |
