Abstract
A ferromagnetic fine line has no loss of spontaneous magnetization even when fabricated ultra-small. The magnetization can be controlled by the proximity of the electrodes and the atomic level structure, and is protected from adsorption of impurities by embedding the ferromagnetic fine line in a nonmagnetic atomic layer.
