摘要：

de Haas-van Alphen measurements in CexLa1-xB6 intermetallics reveal the existence of long-lived quasiparticles for all 0 < x < 1. This is accompanied by the enhancement of the field-dependent effective mass, together with changes to the topology of the Fermi surface developing very early in the series, and with the effective mass eventually exhibiting a maximum near x similar to 0.9. One of the spin contributions to the signal is also observed to disappear at very low x, indicating a spin polarity dependent scattering mechanism. [S0031-9007(99)09074-2].
