Description
Summary:This work presents the results of dynamic simulations of a spin valve sensor. The model used is based on a simple two moment system with random field terms to represent thermal fluctuations. The model predicts the form of the noise output variation with bias field and the effect of applying orthogonal fields to suppress the noise spikes. The origin of the noise lies in the energy degeneracy of the system close to saturation.
