Description
The superconducting transition temperatures (Tc) and Nacute eel temperatures (TN) have been determined for thirty (R1-xR'x)Ni2B2C single crystals. For Tc approx-gt TN, deviations from de Gennes scaling occur that are probably due to crystalline electric field effects. For Tc<TN there is a complete breakdown of de Gennes scaling. In (Dy1-xR'x)Ni2B2C, R'=Lu suppresses Tc an order of magnitude more rapidly than R'=Ho. This breakdown is inferred to arise from pair breaking by collective magnetic excitations. copyright 1996 The American Physical Society
