摘要：
CeCu5 is a Kondo lattice in which antiferromagnetic ordering occurs at 3.9 K. Substituting Cu with Al to achieve CeCu3Al2 results in amplifying the Kondo interaction through addition of conduction electrons, and simultaneously driving the magnetic order down to beyond detection. We present results of specific heat and electrical resistivity that argue for the existence of non-Fermi-liquid behavior founded in a magnetic quantum critical point in CeCu3Al2.
