Co/Pt multilayers for magneto-optical recording

Authors


Abstract

Research News: Magnetic multilayers have emerged as an alternative to amorphous rare-earth transition-metal alloys for application in magneto-optical recording media. Their success has been due to their intrinsic resistance to oxidation and corrosion, large Kerr rotation at shorter wavelengths, ease of preparation, and thermal stability. The Figure shows thermo-magnetically written domains on a Co/Pt disc, written at the given fields.
