23. γH in our undoped sample is larger than the value reported earlier in Ref.. However, their sample had a Tc <15 K and was therefore possibly in the dirty limit.
24. The Hc2 value for H a in the undoped YNi2 B2 C sample was determined from isothermal M-H measurements.
25. This is in qualitative agreement with the variation in Hc2 reported in polycrystalline Pt-doped YNi2 B2 C samples; see G. Fuchs, K.-H. Muller, J. Freudenberger, K. Nenkov, S.-L. Drechsler, S. V. Shulga, D. Lipp, A. Gladun, T. Cichorek, and P. Gegenwart, Pramana, J. Phys. 58, 791 (2002) 10.1007/s12043-002-0173-6

27. In principle Ni and Pt have equal number of electrons outside the filled shell, e.g., Ni: [Ar] 3 d8 4 s2 and Pt: [Xe] 4 f14 5 d9 6 s1. A significant change in N (EF) is therefore not expected.

29. This result is in disagreement with Ref. where a decrease in γn with Pt doping has been reported in samples of YNi2-x Ptx B2 C. We do not observe any decrease in γn with x in our samples.
