OSTI ID:5693758
The compound Pd/sub 2/YSn crystallizes in the cubic Heusler L2/sub 1/ structure and is superconducting with a transition temperature (T/sub c/) of 4.55/sup 0/K. The effect of replacing Y by other paramagnetic rare earths on the superconducting transition temperature has been investigated in the series Pd/sub 2/Y/sub 1-x/R/sub x/Sn (R = Gd, Dy, Ho, Er, Tm and Yb). Results of the T/sub c/ measurements are analyzed in terms of the Abrikosov-Gor'kov theory. Values of the exchange constant J/sub sf/ for interaction between the conduction electron spins and the rare earth spins, are estimated from these measurements.
