Efficient Magnetization Reversal with Noisy Currents
arXiv:cond-mat/0511319 · doi:10.1103/PhysRevLett.96.127203
Abstract
We propose to accelerate reversal of the ferromagnetic order parameter in spin valves by electronic noise. By solving the stochastic equations of motion we show that the current-induced magnetization switching time is drastically reduced by a modest level of externally generated current (voltage) noise. This also leads to a significantly lower power consumption for the switching process.
