Abstract
Solutions of the equation for the superconducting gap including superexchange, spin–fluctuation, plasmon, and phonon pairing mechanisms are obtained. Solutions of the Bardeen–Cooper–Schrieffer equation are approximated by the expression Δk = Δ0(B cos(2ϕ) + (1 − B)cos(6ϕ) at a carrier concentration close to optimal. It is found that the dependence proportional to cos(6ϕ) is due to the spin–fluctuation and phononmediated interactions.
