摘要
Ion implantation in ferrimagnetic garnet epilayers containing bubbles suppresses hard bubbles and defines the propagation tracks for moving bubbles. It has been recognized that the existence of a strain/stress gradient in the vicinity of an implantation boundary is responsible for the formation of charged walls to which bubbles are attached. Two elastic models describing the stress/strain distribution around an implantation boundary are presented. They rely on densities of defects, infinitesimal dislocations and point defects in the continuum approximation.
