摘要：

First order reversal curves (FORC) were simulated and experimentally measured for the first time for laminated antiferromagnetically coupled (LAC) media. Micromagnetic simulation was effectively utilized in order to understand correctly the various peaks in the FORC contours. The result of the simulation was used to assign the experimentally observed FORC contour peaks to different magnetization reversals. It was observed that the FORC could provide more information than the interactions measured by the conventional delta-M method.
