Abstract
We present transport and specific heat measurements on high quality single crystals of UPt3 before and after irradiation by high energy electrons. The induced changes of the superconducting critical temperature are found to depend strongly on the distance from the irradiated surface. The dramatic effects of the irradiation on the specific heat in the superconducting state can then be simply explained in terms of an inhomogeneous distribution of superconducting transition temperatures. The question of the failure of the “universal limit” in the heat transport of UPt3 is reexamined, and the conditions for a clean experimental test are established.
