摘要
Recently proposed antiferromagnetic-coupled (AFQ media is studied in detail. The parameters, which control the switching field of the stabilizing layer and hence, the M(r)delta reduction are understood by theory and experiment. It was observed that the switching field of the stabilizing layer could be controlled by experimental parameters to be on either side of remanence. M(r)delta reduction could be achieved by a reduction of anisotropy constant, thickness or magnetization of the stabilizing layer. The coercivity and thermal stability of the AFC media is larger than that of a single magnetic layer.
