FIG. 1.

Schematic representation of the potential profile, , in a DMS/FE/NS tunnel junction for the electric polarization pointing to the left (a) and to the right (b). The dashed and solid lines show the potential seen by the majority- and minority-spin carriers respectively. The horizontal solid line denotes the Fermi energy, .

FIG. 2.

Total conductance, , (a) and spin polarization (b,c) of injected current in a DMS/FE/NS tunnel junction as a function of potential barrier height (a,b) and the Fermi energy (c) for the polarization of the ferroelectric barrier pointing to the left (solid lines) and pointing to the right (dashed lines) for . In (a) and (b) and ; in (c) and .
