【 摘 要 】

In conclusion, the MR data on Ucu(sub 4+Pi) Al(sub 8-Pi) both below T(sub Nu) as Well as in the nonordered compositions is negative due to the suppression of spin fluctuations. The nega negative value of Delta Rho/Rho, the quadratic behavior with Beta, and the drop in magnitude with Tau are consistent with the spin theory developed by Ueda. Although the study of the properties of this series remains a challenging problem, a better understanding of the effect of non-magnetic disorder on the band scheme, and the CF excitations are in order.
