The feature of magnetic bubble memory devices is nonvolatile and all solid-state. They are now used widely for NC machines, PUS terminals etc., because of their high-reliability and maintenance. free. Materials used for these devices are garnet single crystals. Recent research on high storage density devices is concentrated on ion-implanted bubble devices. These devices are based on the effect of magnetostriction that anisotropy field changes due to the internal stress in the ion-implanted layer of bubble garnets. This paper describes crystal structure and magnetic properties of bubble garnet films. Ion implantation effects in bubble garnets are also reported as a key-technology for ion-implanted bubble devices. [J. Cryst. Soc. Jpn. <B>28</B>, <I>172</I> (1986) ] .
