Abstract 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 coefficient γ (T → 0 ) 1200 mJ/mol.K² is obtained. The temperature independence of the wide peak in specific heat at 1K in magnetic fields further suggests that the high value γ of CeCuGa is due to Kondo effect.
