摘要：

An extremely large Gruneisen parameter (GAMMA) variation has been detected for the heavy-fermion alloys U(Pt1-xPdx)3 (x less-than-or-equal-to 0.15). For pure UPt3 GAMMA(T --> 0) almost-equal-to 75, but drops rapidly with increasing Pd content, amounting to -300 for x = 0.15. The inversion of GAMMA is attributed to the weakening of the antiferromagnetic intersite correlations with increasing Pd content.
