摘要：

We report on the field variation of the fluctuation field (H(f)) in recording media. From theoretical calculations, the field variation of H(f) is found to be governed by the distribution of particle volumes and the distribution of anisotropy fields. The decrease in H(f) arises from the volume distribution while the presence of an anisotropy distribution results in an increase in H(f). Thus when these two effects are present in the sample the field variation of H(f) exhibits a minimum. These predictions are compared with previous experimental results.
