摘要： A spin control mechanism incudes a spin portion and a first channel portion. The spin portion has a magnetic moment that can be reversed and rotated. The first channel portion is provided in contact with the spin portion, and is configured from ferromagnetic insulator. Then, the spin control mechanism controls a direction of the magnetic moment of the spin portion using a spin current generated by a temperature gradient provided to the first channel portion.
