  1. The first three parameters F, m*, and TD were estimated from the Shubnikov–de Haas oscillations for Bc in sample D2. The rest except S were derived from these first three: n is the carrier density, vF the Fermi velocity, EF the Fermi energy, and Γ = πkBTD the Landau-level broadening. The value of n for the α cylinder refers to the sum of the carriers of the two cylinders that occur in the Brillouin zone. To derive EF, we used the linear dispersion relation (EF = vFkF) for the α cylinder and a quadratic one (\({E}_{{{{\rm{F}}}}}={\hslash }^{2}{k}_{{{{\rm{F}}}}}^{2}/(2{m}^{* })\)) for β. The spin-splitting parameter S for Bc is based on11.
