Studies of superconductivity in U(Pt1-xPdx)3 for x<0.006

Abstract We report measurements of the specific heat and resistivity ( T 1− x Pd x ) 3 with x T c − x phase diagram can be constructed, and superconductivity is destroyed for x ∼0.006; this is approximately the same concentration above which the onset of large-moment antiferromagnetism is observed to occur. The splitting of the double superconducting transition increases smoothly with increasing Pd content, and is large enough that for Pd concentrations 0.004 x
