Abstract
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 duri ng the current pulse is deduced from their resistance change. The measureme nts of switching time as a function of applied field and current demonstrat e that the current lowers the energy barrier for switching.
