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.
