摘要：

We have studied the dHvA effect in CeIn3 with particular attention to magnetic filed and spin dependences of the effective mass. We have observed several new frequency branches with effective masses up to 52m(0). The results are discussed in comparison with those of LaIn3 and the band structure calculations based on localized f electron model. The effective mass of d oscillation is found to depend on magnetic field as well as on the direction of spin of the conduction electrons. The difference in the effective masses between the up and down spin electrons is larger for fields parallel to [001] and [111] than [110]. The difference is attributed to the characters of the orbits.
