Abstract

The ΔH (M,ΔM) method and its ability to determine the intrinsic switching field distributions of perpendicular recording media are numerically studied. Strong evidence is presented that this method, which is based on the mean-field approximation, has a well-defined reliability range, corroborating earlier results from micromagnetic and hysteron simulations. Specifically, it is shown that this well-behaved failure appears to be universal and independent from the actual lattice structure.
