## Abstract

The T^2 coefficient of electrical resistivity, A, is compared with the electronic specific-heat coefficient, \\gamma, for a number of Yb-based compounds. It is revealed that many systems including YbCuAl, YbInCu4, YbAl3 and YbCu5 show A/\\gamma^2 values close to 0.4\*10^{-6} \\mu\\Omega cm(mol K/mJ)^2, which is remarkably smaller than that known as the Kadowaki-Woods relation, A/\\gamma^2 = 1.0\*10^{-5} \\mu\\Omega cm(mol K/mJ)^2. Empirically, the compounds with the smaller A/\\gamma^2 values appear to show weak intersite magnetic-correlation and/or to have almost fully-degenerated (J = 5/2 or 7/2) ground states.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
