Abstract
A bubble memory with a hybrid junction formed between a first propagation track defined by a boundary between an implanted area and a non-implanted area and a second propagation track defined by a sequence of deposited patterns. The overlap zone between the tracks has a surface substantially equal in size to the magnetic bubble. The boundary cleared by the magnetic bubble has a direction perpendicular to an easy magnetization axis of the magnetic material of the memory, and an implanted area is formed beneath one leg of the deposited pattern.
