Magnetic domain wall motion element and magnetic array

A magnetic domain wall motion element comprising:

• a magnetic domain wall motion layer;
• a first magnetization fixing portion;
• a second magnetization fixing portion;
• a first wiring;
• and
• a second wiring,
• wherein the magnetic domain wall motion layer has a first magnetization fixed area, a second magnetization fixed area, and a magnetic domain wall motion area,
• the magnetic domain wall motion area is sandwiched between the first magnetization fixed area and the second magnetization fixed area in a first direction,
• the first magnetization fixing portion is connected to the first magnetization fixed area,
• the second magnetization fixing portion is connected to the second magnetization fixed area,
• the first wiring is connected to the first magnetization fixing portion,
• the second wiring is connected to the second magnetization fixing portion,
• each of the first wiring and the second wiring has a first part extending in the same direction as a second direction intersecting the first direction and a lamination direction with respect to the magnetic domain wall motion layer, and
• magnetization of the first magnetization fixed area is oriented in a direction which is an outer product of a direction in which the magnetic domain wall motion layer extends with respect to a first connection surface between the first magnetization fixing portion and the first wiring, and a direction in which the first part extends in the second direction with respect to the first connection surface.
