Description

The electrical resistance measurements of the UCu4-xNixAl8 were performed in the temperature range 30 mK-4.2 K. Also the samples without Ni but with various Al/Cu ratio were investigated. All these compounds exhibit strong decrease in R(T) plot below 1 K which results from a presence of CuAl2 as impurity. The ScCu4+xAl8-x alloys exist as the single-phase materials for the composition range 0 ≤ x ≤ 2.15. At low temperatures the alloys are weakly paramagnetic whereas at higher temperatures weakly diamagnetic properties are observed. Their electrical resistivity is low and weakly temperature dependent. No anomalies in both χ(T) and ρ(T) plots can be detected. (orig.)
