In electron-doped cuprates, such as La 2− x Ce x CuO 4, a link has been identified between critical temperature and electron scattering off commensurate antiferromagnetic spin fluctuations. This correlation highlights low-energy spin fluctuations as the primary pairing mechanism, contrasting with hole-doped cuprates and suggesting the need to extend the Bardeen–Cooper–Schrieffer theory.
