Local resonant conductance in magnetic tunnel junctions
Source abstract
Abstract
Using a simple tight-binding model and the Kubo formula we have calculated the lateral distribution of the tunneling conductance across a magnetic tunnel junction probed by scanning tunneling microscopy. We find that the presence of an impurity within the barrier layer can cause a sharp spike in the conductance distribution, in agreement with recent experiments.
