On the ${}^{12}$C/${}^{13}$C carbon isotope effect in the quasi one-dimensional superconductor Sc${}_3$CoC${}_4$

Christof D. Haas, Georg Eickerling, Ernst-Wilhelm Scheidt +10

Sc${}_3$CoC${}_4$ is the only superconductor in the group of the isotypic carbides Sc${}_{3}M$C${}_4$ ($M$ = Mn, Fe, Ru, Os, Co, Rh, Ir, Ni), rendering it into an ideal benchmark system to s…
