摘要

Auger and photoemission studies for Y(Rh_1-xRu_x)₄B₄ superconductors elucidate the mechanism for the abrupt drop in T_c near x=0.5. The B p-states admix more strongly with Ru than Rh d-states, thereby yielding low-T_c 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-T_c values in ternary boride compounds.
