FIG. 2.

(Color online) Consider a pinhole of one atom in diameter and (four-atom) long embedded in a MTJ. (a) shows the conductance (measured in ) vs energy of incoming electron in the parallel alignment (PA) for both majority and minority spin bands; (b) is vs for antiparallel alignment (APA); in (c) nonlinear characteristic is plotted for both PA and APA configurations; (d) shows the MR dependence on bias voltage.

(Color online) Same quantities are plotted as in Fig. 2 after averaging over an ensemble of pinholes.

(Color online) The MR of a wide pinhole of five atoms in diameter compared with an all-metal GMR spin valve.
