Abstract / Description:The Cu substitution by Zn and Ni impurities and its influence on the
mass renormalization effects in angle-resolved photoelectron spectra
(ARPES) of Bi2Sr2CaCu2O8-delta is addressed. We show that the
nonmagnetic Zn atoms have a much stronger effect in both the nodal and
antinodal parts of the Brillouin zone than magnetic Ni. The observed
changes are consistent with the behavior of the spin resonance mode as
seen by inelastic neutron scattering in YBCO. This strongly suggests
that the "peak-dip-hump" and the kink in ARPES on the one side and
neutron resonance on the other are closely related features.
