It sees the formation of a many-body ground state and involves a log-T contribution to resitivity at low temperatures.
Eigler used an ellipse of cobalt atoms with an atom at one focus in an experiment that observed the resonance associated with this phenomenon at both foci. For this effect to occur with the presence of large spin atoms, the magnetic anisotropy must produce degenerate ground state levels accompanied by a spin flip in the large atom, and it arises in host materials with magnetic (*) impurities as the conduction electrons are scattered and screen the impurity. It sees the formation of a many-body ground state and involves a log-T contribution to resitivity at low temperatures. For 10 points, identify this effect which was first observed with the divergence of the resistance of at temperatures close to the absolute zero, and is named for a Japanese physicist.
