Mathematical modelling of ferromagnetic resonance in a system of Stoner-Wohlfarth particles

Abstract A computer model has been developed to stimulate ferromagnetic resonance on a 5×5×5 array of Stoner-Wohlfarth particle using the Landau-Lifshitz equation. A distribution of particle volumes and easy-axis directions was included. The model gives good agreement with experimental measurements of CrO 2 particles.
