A review is given on the exchange switching of ferromagnetic metallic junctions under the effect of a low threshold current. A dramatic (orders of magnitude) threshold current reduction is achieved under conditions that include the dominance of the current-driven nonequilibrium spin injection, the optimum relation between spin resistances of the layers, and the application of an external magnetic field near the reorientation phase transition point.
