Analysis of Complex Transverse Susceptibility Method for Determination of Volume and Anisotropy Field Distributions in Recording Media

In this paper we present a quantitative comparison between the results obtained for volume and anisotropy distributions using the micromagnetic model and the model from Ref. [2].Here we present a systematic quantitative analysis of the influence of the AC field amplitude and of the interactions between particles on the complex transverse susceptibility method for determination of volume and anisotropy field distribution in recording media .
