摘要：

The effect of Gd and Ni impurities on the upper superconducting transition temperature of UPt(3) (T(c)(+) = 0.55 K) has been studied by means of resistivity measurements. Surprisingly, we find that paramagnetic Gd impurities suppress T(c)(+) at the same rate as non-magnetic Y or Th impurities, yielding further support for non-s-wave pairing. Ni impurities also suppress T(c)(+), but do not dissolve homogeneously in the UPt(3) matrix.
