Abstract
The nonequilibrium spin polarization of electrons is calculated under the conditions of spin injection by current passing from one ferromagnetic film to another in a magnetic junction. It is shown that the nonequilibrium spin concentration may substantially increase with an appropriate choice of parameters of the films and operation conditions. This leads to a decrease in the threshold current density required for switching the magnetic junction by several orders of magnitude.
