By use of the scanning MOKE measurement, we observe that two domain walls are moved simultaneously by spin polarized current at the current density of 1.43 x 10(12) A/m(2). The domain wall speed is estimated to be about 1.5 m/s, determined by the domain wall displacement (750 nm) and the current pulse duration (500 ns). From in situ resistance measurement, the temperature of the nanowire rises up to 700 K when the domain wall moves at such the high current density.
