Stochastic resonance in a system of ferromagnetic particles
arXiv:cond-mat/9505136 · doi:10.1103/PhysRevE.51.4159
Abstract
We show that a dispersion of monodomain ferromagnetic particles in a solid phase exhibits stochastic resonance when a driven linearly polarized magnetic field is applied. By using an adiabatic approach, we calculate the power spectrum, the distribution of residence times and the mean first passage time. The behavior of these quantities is similar to their corresponding ones in other systems in which stochastic resonance has also been observed.
