  • Process for producing a layer having a high magnetic anisotropy in a ferrimagnetic garnet
    Patent number: 4711694
    Abstract: Process for producing a ferrimagnetic garnet layer having a high magnetic anisotropy on an amagnetic substrate, wherein it comprises the stages of forming at least one ferrimagnetic garnet layer by epitaxy from the amagnetic substrate, high dose ion implantation in the ferrimagnetic garnet layer in order to produce defects therein and heating the entity in the presence of a reducing agent to a temperature between 250.degree. and 450.degree. C.Application to the production of bubble stores with non-implanted propagation patterns.
    Type: Grant
    Filed: October 28, 1985
    Date of Patent: December 8, 1987
    Assignee: Commissariat a l'Energie Atomique
    Inventors: Thierry Capra, Philippe Gerard
  • Process for the production by catalysis of a layer having a high magnetic anisotropy in a ferrimagnetic garnet
    Patent number: 4624858
    Abstract: Process for producing a ferrimagnetic garnet layer having a high magnetic anisotropy on an amagnetic substrate, wherein it comprises the stages of forming at least one ferrimagnetic garnet layer by epitaxy from the amagnetic substrate, implanting ions in the ferrimagnetic garnet layer in order to produce defects therein, depositing on the ferrimagnetic garnet layer a metal layer able to activate and diffuse hydrogen into said garnet layer and heating under a hydrogen atmosphere of the complete structure, in order to bring about the diffusion of hydrogen into the ferrimagnetic garnet layer.Application to the production of bubble stores with non-implanted propagation patterns.
