Re-entrant superconductivity in a magnetically ordered superconductor: La(1-x)Gd(x)Ru/sub 2/
Technical Report

OSTI ID:5777605
We have measured the critical temperature (Tc) and the upper critical magnetic field (Hc2) of La(1-x)Gd(x)Ru2. At low concentrations of the magnetic impurity (Gd), the suppression of Tc follows the expected Abrikosov-Gorkov (A-G) pair breaking curve. However, for larger concentrations, strong deviations below A-G are observed. Samples in this region (4. < or = x < or = 5. at. %) exhibit two Tc's. La(1-x)Gd(x)Ru2 is known to order magnetically, probably as a spin glass, and the magnetic ordering temperature (T sub M) has been measured in the normal state. This T sub M curve intersects the Tc curve in the concentration range where the Tc curve is re-entrant and we therefore attribute the re-entrant Tc behavior to the magnetic ordering of the Gd(3+) ions.
