Magnetic bubble device |
摘要 |
A magnetic bubble device includes ion-implanted bubble propagation tracks of meandering cord-like configuration to assure improved bubble propagation characteristic. Amplitude of a region in which inplane magnetization layer is absent or alternatively thickness thereof is smaller than that of other region, as measured in the direction perpendicular to the bubble propagating direction, is not greater than 7/8 of a pitch of the meandering pattern in the bubble propagating direction. The amplitude is more preferably selected so as to meet the condition that 1/4</=W/P</=3/4 for assuring much stabilized bubble propagating operation.
