摘要：

Remanence measurements have been proposed as a means of estimating the amount of intergranular exchange present in thin film recording media. A micromagnetic model is used to compute remanence curves starting from a de-saturated state and an ac-erased state, for a range of media parameters. It is found that the amount of intergranular exchange is the most important parameter determining the difference delta-M between these two curves, however the interpretation is clouded somewhat by the effect of anisotropy and other parameters.
