Title: Itinerant effects and enhanced magnetic interactions in Bi-based multilayer cuprates

The cuprate high temperature superconductors exhibit a pronounced trend in which the superconducting transition temperature, T c, increases with the number of CuO₂ planes, n, in the crystal structure. We compare the magnetic excitation spectrum of Bi₂₊xSr₂₋xCuO₆+δ (Bi-2201) and Bi₂Sr₂Ca₂Cu₃O₁₀₊δ (Bi-2223), with n = 1 and n = 3 respectively, using Cu L₃-edge resonant inelastic x-ray scattering (RIXS). Near the anti-nodal zone boundary we find the paramagnon energy in Bi-2223 is substantially higher than that in Bi-2201, indicating that multilayer cuprates host stronger effective magnetic exchange interactions, providing a possible explanation for the Tc vs. n scaling. In contrast, the nodal direction exhibits very strongly damped, almost non-dispersive excitations. As a result, we argue that this implies that the magnetism in the doped cuprates is partially itinerant in nature.
