The specific heat of a melted-textured-growth (MTG) YBa2Cu2.99Li0.01Ox crystal has been measured from 1.8 to 30 K in different fields up to 9 T parallel to the c-axis by the thermal relaxation technique. The defects induced by Li-doping and the paramagnetic centres have a strong effect on the low-temperature specific heat. The electronic specific heat Ce(T,H)/T at lower temperatures (T<5 K) follows αT at 0 T and AH1/2 in the magnetic field, and can be scaled on a line, Ce(T,H)/TH1/2 = F(T/H1/2). These results are consistent with that of the d-wave superconductor predicted theoretically by Volovik, indicating that a Li-doped MTG-YBa2Cu2.99Li0.01Ox crystal should be a d-wave superconductor.

“…where 1 ÿ TfT gives the fraction of bosons localized within the CuO 6 octahedra (one plane) or CuO 5 pyramids (multiplane), which as a result tilt and form the stripes [6,8]. In YBa 2 Cu 3 O 6:95 near optimal doping the function T has been approximated by the Fermi function [3] T 1 exp TÿT 0 b ÿ1 with T 0 T c ÿ 10 K and b 5 K, when using 0:8 in ft and T 200 K. These are fixed by the Hall effect.…”
