Anti-ferromagnetically coupled recording media with enhanced RKKY coupling

摘要

An anti-ferromagnetically coupled (“AFC”) magnetic recording medium with RKKY coupling between spaced-apart magnetic layers comprising a non-magnetic substrate having a surface, and a layer stack atop the substrate surface. The layer stack comprises, in overlying sequence from the substrate surface: a magnetic stabilization layer, a non-magnetic spacer layer, and a main magnetic recording layer the main magnetic recording layer comprises, in overlying sequence from the non-magnetic spacer layer: (i) a top interface layer, (ii) a Cr alloy magnetic layer, and (iii) a top magnetic layer.
