Fermi-Surface-Sheet Dependent Electron-Phonon Coupling in a Borocarbide Superconductor YNi_{2}B_{2}C
{{output}}
We performed de Haas-van Alphen (dHvA) oscillation measurements and band-structure calculations for YNi_{2}B_{2}C. Our improved band structure successfully explained the origins of the large dHvA frequencies β and ζ, which were inexplicable in previous works... ...
