Universal Heat Conduction in Ce1-xYbxCoIn5: Evidence for Robust Nodal d-wave Superconducting Gap

Y. Xu, J. K. Dong, L. I. Lum +9

In heavy-fermion superconductor Ce${}_{1-x}$Yb${}_x$CoIn${}_5$ system, Yb doping was reported to cause a possible change from nodal $d$-wave superconductivity to a fully gapped $d$-wave…
