The electrical resistivity of the cubic Kondo system Ce x La 1Γx B 6 (x ΒΌ 0:1-0.65) has been measured. Non-Fermi liquid behavior is found in paramagnetic phase I over the wide Ce concentration range. Heavy fermion behavior is found in ordered phases of Ce 0:65 La 0:35 B 6 . The mass enhancement of q
The nesting of the Fermi surfaces of an electron and a hole pocket separated by a nesting vector Q and the interaction between electrons gives rise to itinerant antiferromagnetism. The order can gradually be suppressed by mismatching the nesting and a quantum critical point is obtained as the N eel
