The phenomenon of stochastic resonance (SR) has been mainly studied in one-dimensional systems with additive noise. We show that in higher dimensional systems and in the presence of multiplicative noise, a non-linear magnetic system with a strongly periodic current can show behavior similar to that of SR but only for frequencies below the ferromagnetic resonance (FMR) frequency of the system. Such a phenomena can provide an effective way to suppress low frequency noise in spin valve magnetic sensors.
