摘要：

The dependence of the saturation magnetization of the underlayer which maximizes the signal-to-noise ratio on the exchange coupling in the anti ferromagnetically coupled double-layered medium was investigated using micromagnetic computer simulation. The SNR was found to increase with increasing the inter-layer coupling until it decreased when the coupling constant exceeded beyond the optirnurn value. (C) 2002 Elsevier Science B.V.
