摘要：

The thermally-activated magnetization reversal process of the lower layer in antiferromagnetically coupled media is investigated. The temperature dependence of the hysteresis loops is used to determine the magnetic parameters of the lower layer and to predict its reversal time. We discuss this reversal time both with and without transitions recorded in the media, and present an experimental technique that demonstrates thermally activated writing of the lower layer.
