Abstract :
A phenomenological model for calculating the giant magnetoresistive (GMR) response of magnetic systems and devices is described. The model can easily be incorporated with minor revisions into most micromagnetic models and accounts for dependencies on sample size, shape and internal electrical current and magnetization distributions. The application of the model to the computation of the MR response of a granular thin-film sample is presented.
