Abstract
Plots of the real and imaginary components, chi'(omega) and chi ''(ome ga), of the complex ac susceptibility of a distribution of magnetic pa rticles (magnetic fluid) have been generated using a classical harmoni c oscillator model. To achieve a better fit between experimental data and the model, the model was extended to include Gamma distribution fu nctions to represent the distribution of the particle sizes and their magnetic properties. After-effect functions of the magnetic fluid are also determined.
