    • -1. This assumption corresponds to 3.3 carriers per f.u. for a = 5 Å or to 2.8 carriers per f.u. for a = 4 Å, which seem to be typical values for them. The formula unit (f.u.) is to include only one rare-earth ion.

    • 6 is considered to be a quartet. However, we note that the Fermi-liquid behavior in this system is observed only below 0.5 K, which is much lower than the quadrupolar-ordering temperature of 3.3 K [N. Sato, A. Sumiyama, S. Kunii, H. Nagano, and T. Kasuya, J. Phys. Soc. Jpn. 54, 1923 (1985)]. Therefore, the degeneracy relevant to the Fermi-liquid behavior should be much smaller than 4.

    • 2 of these metals is hence much smaller than Eq. (4). Here, note that the theory [10] we use in the present work is based on the strong-coupling case (m*/m ≫ 1), which is apparently not the case of these metals. For such weak-coupling cases, deviation from the KW relation is suggested theoretically [K. Miyake, T. Matsuura, and C. M. Varma, Solid State Commun. 71, 1149 (1989)].
