We present a theory of the dependence of the energy and the damping of this mode on layer separation $d$. Based on these results, we discuss the possibility of realizing transport-current driven pseudospin-transfer oscillators in semiconductors.4+ pages, 3 figures, submittedMesoscale and Nanoscale PhysicsStrongly Correlated Electronstext
