Abstract

The calculation of the magnetoresistance of tunnel junctions with parallel paths of conduction was discussed. The tunnelling through all the states, that existed at the electrode-barrier interfaces by placing reservoirs directly across the barriers, was calculated. The analysis showed that tunnelling currents exhibited minority-spin polarization.
