title = "Atomic substitution and carbon isotope effect in superconducting MgCNi 3",
abstract = "The superconductor MgCNi3 has been chemically doped by substitution of Ru and Fe for Ni and B for C. Neither ferromagnetism nor increasing TC is observed, suggesting that MgCNi3 has optimal superconducting properties at its intrinsic composition and electron count The effect of Carbon isotope substitution on Tc is reported: the carbon isotope effect coefficient is αc = 0.54±0.03. This indicates that carbon-based phonons play a critical role in the superconductivity.",
