説明

Magnetic bubble played an important role in the field of “Magnetics.” This technology was born from the combination of magnetic films with perpendicular magnetization and control of domain propagation. Bobeck presented the first paper in INTERMAG con ference in 1968, and now above 50 papers on the magnetic bubble are presented in INTERMAG con ference every year.<BR>In conventional magnetic bubble devices, permalloy patterns, such as T bars, chevrons and half-discs, are used and contiguous disc devices using ion implanta tion are developing in bubble devices with below 1 μm diameters.<BR>Bubble lattice devices and current access devices, such as a dual conductor system, are also hopeful. Magnetic bubbles are higher bit density memory compared with semiconductor memory, but their cost is a little expensive. Efforts must be done in the future in cost reduction and improvement in switching speed.
