摘要：

We present resistivity measurements at ambient pressure on high purity crystals of YNi3 and Ni3Al in the temperature range from 50 mK to 7 K. Although both systems are well in their low moment ferromagnetic state, there is no evidence for a T-2-temperature dependence of the resistivity as would be expected from Fermi liquid theory. Instead, we observe an anomalous temperature exponent of 1.5-1.6 down to low temperatures. (C) 2003 Elsevier Science B.V. All rights reserved.
