Low-temperature magnetic susceptibility and resistivity measurements and electron probe microanalysis of Y sub 1-x U sub x Pd sub 3

Low temperature magnetic susceptibility and resistivity measurements of Y sub 1-x U sub x Pd sub 3 (x=0.2) were extended down to millikelvin temperatures. One sample showed Curie-Weiss-like paramagnetic susceptibility between 50 mK and 2K. Another small sample appeared to have nearly constant susceptibility between 400 mu K and 120 mK. The signal arising from paramagnetic impurities has been estimated from the susceptibility of undoped YPd sub 3 measured between 600 mu K and 170 mK. No signature of superconductivity was observed in the resistivity measurements down to 5 mK. Electron probe microanalysis showed that the sample composition was modulated on a scale of tens of micrometers.
