✦ Synopsis

The electrical resistivity of the cubic Kondo system Ce x La 1Àx B 6 (x ¼ 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 quasiparticles in this compound is strongly dependent of the magnetic field.
