We report a systematic high-resolution angle-resolved photoemission
spectroscopy on high-Tc superconductors Bi2Sr2Can-1CunO2n+4 (n=1–3)
to study the origin of many-body interactions responsible for superconductivity.
For n=2 and 3, a sudden change in the energy dispersion, so called
“kink”, becomes pronounced on approaching (π,0) in the superconducting
state, while a kink appears only around the nodal direction in the
normal state. For n=1, the kink shows no significant temperature
dependence even across Tc. This could suggest that the coupling of
electrons with Q=(π,π) magnetic mode is dominant in the superconducting
state for multilayered cuprates, while the interactions at the normal
state and that of single-layered cuprates have a different origin.
