ABSTRACT:
The present invention relates to a magnetic ring unit and a magnetic memory device; an object of the invention is to control the direction of rotation of the magnetic flux freely and with high reproducibility in a simple structure without using a thermal process such as pinning; and a magnetic ring unit is formed of a magnetic ring in eccentric ring form where the center of the inner diameter is located at a decentered position relative to the center of the outer diameter.
