    摘要: Herein disclosed is a laminated magnetic bubble device of a multiple layer structure composed of at least one thin magnetic film having low coercive force and vertically oriented anisotropy which can allow easy generation and erasure of a magnetic bubble, and at least one thin magnetic film having high coercive force and vertically oriented anisotropy which will not be affected by a magnetic field of low level used for generating the magnetic bubble in the thin film of low coercive force.
