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.
