ABSTRACT:
Magneto-optical memory having a substrate of a material which is transparent for the visible-to-infrared spectral range, on which there are provided, in this sequence, a dielectric layer which is transparent for the visible-to-infrared spectral range and has a refractive index which is higher than the refractive index of the substrate and constitutes a diffusion barrier layer for oxygen and/or water, an in essence amorphous and/or in essence micro-crystalline magneto-optical layer with uniaxial anisotropy and a magnetic ordering temperature higher than ambient temperature and a top layer which acts as a reflection or interference layer and as a diffusion barrier layer for oxygen and/or water, the dielectric layer being a layer which is deposited from organic silicon materials by means of a PCVD process.
