ABSTRACT:
A writing device can change the direction of the magnetic moment in a magnetic shift register, thus writing information to the domains or bits in the magnetic shift register. Associated with each domain wall are large magnetic fringing fields. The domain wall concentrates the change in magnetism from one direction to another in a very small space. Depending on the nature of the domain wall, very large dipolar fringing fields can emanate from the domain wall. This characteristic of magnetic domains is used to write to the magnetic shift register. When the domain wall is moved close to another magnetic material, the large fields of the domain wall change the direction of the magnetic moment in the magnetic material, effectively “writing” to the magnetic material.
