Abstract

We report systematic high-resolution angle-resolved photoemission Spectroscopy (ARPES) on Bi2Sr2Can-1Cu nO2n+4 (n = 1-3) to study the electronic structure near the Fermi level (EF) and the low energy excitation. Comprehensive ARPES data on the sudden break in the energy dispersion near EF (kink) as a function of momentum, temperature, and number of CuO2 layers indicate that the coupling of electrons with Q = (π, π) magnetic mode is dominant in the superconducting state for multi-layered cuprates.
