  • METHOD FOR MANUFACTURING A PART OR A SUPPORTED MICROSTRUCTURE BY LASER EXPOSURE OF A METAL OXALATE LAYER
    Publication number: 20190106790
    Abstract: The invention relates to a process for the manufacture of a metal, ceramic or composite part or of a supported metal, ceramic or composite microstructure by laser irradiation starting from metal oxalates, and also to the part and the microstructure obtained by said process, and to their uses.

  • Use of oxidable spinels for optical recording
    Publication number: 20050014097
    Abstract: The present invention relates to a method of recording data in digital form on a write-once read-many optical medium comprising a sensitive film based on a metal oxide of the oxidizable spinel type. Regions of the sensitive film are heated, locally and in succession, under conditions allowing oxidation of the oxidizable metal ions of the oxide. In the optical medium thus recorded, the virgin regions, which are not modified by the write operation, are oxidizable and change color after heat treatment in an oxidizing atmosphere.

  • Composite material for magnetooptic recording its preparation and its use
    Patent number: 6017645
    Abstract: Composite material for magnetooptic recording, comprising a thin layer deposited on a non-magnetic solid substrate. The said thin layer is a polycrystalline layer consisting of microcrystals having a structure of a vacant-site spinel ferrite, based on iron, cobalt and transition metals. By virtue of a particular process for producing the thin layers, enabling especially the size of the crystallites to be increased, it is possible to optimize the magnetic and magnetooptic properties and to obtain thin layers having, for example, a remanent Faraday rotation and a coercive field which are greater, respectively, than 1 degree per micron for the Faraday rotation and 1000 Oe for the coercive field.
