摘要：

Anomalous magnetoresistance in Ce1-xLaxSb and Ce1-xLaxBi was studied systematically both experimentally and theoretically. It is shown that the unusually strong positive longitudinal magnetoresistance is due to the longitudinal multi-Q charge density wave formation inducing gaps on the Fermi surface of each Landau level, while the strong negative longitudinal magnetoresistance is due to the formation of a GAMMA8 magnetic polaron lattice.
