摘要：

We present experimental results on the magnetic susceptibility, electrical resistivity and Hall coefficient for the normal state of Ce2CoIn8 in the temperature range 2-300 K. These results confirmed the heavy-fermion behaviour of Ce2CoIn8. The resistivity shows a linear temperature dependence in the low-temperature range, which develops remarkably with increasing pressure. This suggests that Ce2CoIn8 is near the quantum critical point.
