Gap-function symmetry and spin dynamics in electron-doped cuprate superconductors

Year: 2007

Type: article

Abstract: An antiferromagnetic (AF) spin fluctuation induced pairing model is proposed for the electron-doped cuprate superconductors. It suggests that, similar to the hole-doped side, the superconducting gap function is monotonic ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$ wave and explains why the observed gap function has a nonmonotonic ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}$-wave behavior when an AF order is taken into account. Dynamical spin susceptibility is calculated and shown to be in good agreement with the experiment. This gives a strong support to the proposed model.
