Beschreibung
Zusammenfassung:A magneto-optical recording medium comprising a substrate and a recording layer, the recording layer comprising a bilayer structure consisting of a first layer on which a magnetic second layer is deposited, the second layer demonstrating perpendicular magnetic anisotropy and a saturation remanence of at least 90%, whereby the magnetic material of the second layer comprises an oxide of iron, and the first layer comprises an oxidic material whose in-plane lattice parameter differs from that of the magnetic material, the growth of the second layer upon the first layer being at least locally epitaxial.
