摘要：

The specific heat, C, and the magnetic susceptibility, chi, have been measured on the pseudo-ternary compounds U1-xLaxRu2Si2 (0 less-than-or-equal-to x less-than-or-equal-to 0.3). The broad maximum of chi observed in URu2Si2 at 55 K turns to a sharp cusp anomaly, with increasing La concentration. From the results, we suggest that the broad peak of chi in URu2Si2 originates from the AF fluctuations.
