abstract = {Among all transition metals, palladium (Pd) has the highest
density of states at the Fermi energy at low temperatures
yet does not fulfill the Stoner criterion for
ferromagnetism. However, close proximity to magnetism
renders it a nearly ferromagnetic metal, which hosts
paramagnons, strongly damped spin fluctuations. Here we
compare the total and the differential conductance of
monoatomic contacts consisting of single Pd and cobalt (Co)
atoms between Pd electrodes. Transport measurements reveal a
conductance for Co of 1G0, while for Pd we obtain 2G0. The
differential conductance of monoatomic Pd contacts shows a
reduction with increasing bias, which gives rise to a
peculiar Λ-shaped spectrum. Supported by theoretical
calculations, we correlate this finding with the lifetime of
hot quasiparticles in Pd, which is strongly influenced by
paramagnon scattering. In contrast to this, Co adatoms
locally induce magnetic order, and transport through single
cobalt atoms remains unaffected by paramagnon scattering,
consistent with theory.},
