ABSTRACT:
Pt/Co multilayer materials systems having a thin metal interlayer possess superior room temperature coercivity, a square polar Kerr hysteresis loop, sufficient polar Kerr rotation, and are suitable for magneto-optical recording.
These material systems allow the reading and writing of information from the substrate side of the multilayer film.
