Abstract

The low-temperature specific heats of ScTc2 and ScRe2 are reported. The newly discovered record highT c for a Laves phase (10.9 K) in ScTc2 is explained qualitatively by its factor of two largerN(0) than in ScRe2 (T c=0.93 K). Comparison of the data for ScTc2 with that for HfV2 (T c=8.4 K), which has three times theN(0) as for ScTc2, suggests that the electron-phonon coupling strength is also an important factor in the highT c of ScTc2.
