Abstract

The electrical resistivity of the cubic Kondo system Ce_x La_{1 - x} B₆ ( x = 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 B₆. The mass enhancement of quasiparticles in this compound is strongly dependent of the magnetic field.
