摘要

Auger and photoemission studies for Y(Rh1-xRux)4B4 superconductors elucidate the mechanism for the abrupt drop in Tc near x=0.5. The B p-states admix more strongly with Ru than Rh d-states, thereby yielding low-Tc values for Ru-rich compounds due to broadening of the d-band feutures. These effects underlie a previous suggestion that the preservation of Rh4 tetrahedral units is essential for high-Tc values in ternary boride compounds.
