摘要
Specific heat in applied magnetic fields were measured to a low temperature 0.08 K and resistance to 0.5K.The specific heat shows a wide peak at 1 K,and a high value of the electronic coefficientγ(T→0)1200 mJ/mol·K^(2) is obtained.The temperature independence of the wide peak in specific heat at 1K in magnetic fields further suggests that the high valueγof CeCuGa is due to Kondo effect.
