Description

Superconducting UPt3 is characterized by a novel and complex magnetic field-temperature phase diagram, with two superconducting transitions at Tc1 and Tc2 in zero field. We have studied the effects of Pd and Y impurities on the zero field superconducting properties of UPt3. Resistance measurements show that both dopants increase the residual resistivity and decrease the spin fluctuation temperature in the normal state. Tc1 is depressed by both dopants, but more effectively by Pd. |Tc1 - Tc2| is essentially unaffected by Y doping, but increases dramatically with Pd doping
