The effect of pulsed currents on magnetization reversal were studied
on single ferromagnetic nanowires of diameter about 80 nm and 6000 nm
length. The magnetization reversal in these wires occurs with a jump
of the magnetization at the switching field Hsw, which
corresponds to unstable states of the magnetization. A pulsed current
of about was injected at different values of the
applied field close to Hsw. The injected current triggered the
magnetization reversal at a value of the applied field distant from
the switching field by as much as 20%. This effect of current-induced
magnetization reversal is interpreted in terms of the action of the
spin-polarized conduction electrons on the magnetization.
