摘要：

Electrical contacts to single isolated Nickel nanowires (80 mu in diameter, 6000 mu in length), pulsed current densities of about 10(7) A/cm(2) and a Weathstone bridge of a 1 GHz bandwidth allow detection of the magnetization switching in static magnetic fields. The temperature of the nanowires during the current pulse is deduced from their resistance change. The measurements of switching time as a function of applied field and current demonstrate that the current lowers the energy barrier for switching.
