摘要：

We theoretically study ferromagnetic (FM) fluctuations in the heavily overdoped region of cuprate superconductors. To explore the origin of FM fluctuations, we evaluate the spin susceptibilities of a single-band Hubbard model within the fluctuation exchange approximation. Model parameters are derived using the Wannierization technique and the constrained random phase approximation method based on the maximally localized Wannier functions. The constrained random phase approximation calculations reveal that the on-site Coulomb interaction decreases with an increase in hole doping. This reduction of the on-site Coulomb interaction leads to the emergence of FM fluctuations in heavily overdoped cuprates.
