Abstract
We have studied the electrical conductance in Au nanowire containing 0.07 at.% Fe ions and Cu nanowire containing 13 at.% Mn ions with mechanically controllable break junction technique to investigate the magnetic impurity effects in the atomic-sized conductance. We observe not only conductance steps at the integer multiples of G0 = 2e2/h, but also steps deviating from them. The scattering between the conduction electrons and impurity ions lifts the spin degeneracy of the transmission probability, which may be responsible for the deviation.
