摘要：

The current-voltage characteristics on point contacts of a new Kondo lattice compound CeCu//6 were investigated experimentally at liquid helium temperatures. The spectra of CeCu//6 were decomposed into symmetric and asymmetric parts and were compared with those of the reference compound LaCu//6. The asymmetric part shows a sharp step near 2 to 2. 5 mv bias voltage while the symmetric part shows a logarithmic dependence on bias voltage near 10 mv.
