A classical (Y,Sm,Lu,Ca)3 (Fe,Ge)5O12 bubble garnet has been implanted with 1.5×1016 H+2 cm−2 at 60 keV either directly or through a predeposited 100‐A‐thick silica layer. The damage and ion implant profile were determined as well as the maximum strain and some magnetic properties of an as‐implanted sample. The evolution of certain of these parameters have been studied after different well‐chosen annealing treatments. From these observations it has been possible to dissociate the abnormal ‘‘chemical’’ from the usual magnetic effects. A certain mechanical contribution of the silica overcoat to the implanted layer has been displayed.
