Abstract
A method of controlling a magnetization state using an imprinting technique may be provided. The method may include moving first and second magnetic structures, which have different magnetization states, toward each other and changing a magnetization state of the first or second magnetic structure, when a distance between the first and second magnetic structures is reduced. A magnetic field, which is produced by a magnetization state of one of the first and second magnetic structures, may be used to align a magnetization state of the other, when the magnetization state of the first or second magnetic structure is changed.

A method of controlling a magnetization state using an imprinting technique, the method comprising:
- moving a first magnetic structure and a second magnetic structure toward each other, the first and second magnetic structures having different magnetization states;
- changing a magnetization state of the first or second magnetic structure when a distance between the first and second magnetic structures is reduced;
- and
- using a magnetic field produced by a magnetization state of one of the first and second magnetic structures to align a magnetization state of another of the first and second magnetic structures when the magnetization state of the first or second magnetic structure is changed,
- wherein, when the first magnetic structure or the second magnetic structure has a patterned shape, the magnetization state of the first magnetic structure or the second magnetic structure is changed at a portion, in which the first and second magnetic structures are adjacent to or overlapped with each other.

- using a magnetic field produced by a magnetization state of one of the first and second magnetic structures to align a magnetization state of another of the first and second magnetic structures when the magnetization state of the first or second magnetic structure is changed;
- and
- applying a magnetic field to each of the first and second magnetic structures, before the moving of the first and second magnetic structures toward each other,
- wherein the applying of the magnetic field is performed to change a magnetization state of the first magnetic structure and a magnetization state of the second magnetic structure to allow the first and second magnetic structures to have different magnetization directions.
