Abstract

A systematic numerical study is performed on the ΔH (M,ΔM) method and its ability to determine the intrinsic switching field distributions of perpendicular recording media in the presence of locally varying intergranular exchange and magnetostatic interactions. It is found by means of evaluating various reliability measures that the overall robustness of the ΔH (M,ΔM) method is only slightly reduced due to the presence of randomness in both the exchange and magnetostatic interactions, at least within the parameter range that is relevant for typical recording media.
