Dual Control Theory of Spintronics

Abstract

For explaining about the quantized Barkhausen jump that is observed in iron nanowires system, we introduced the two type spin Josephson junction models. One type of these system are composed of the sandwich structure by FM (ferromagnet)/AM (anti ferromagnet)/FM junction, and its dual junction is consists of the sandwich structure by AF/FM/AF junction. In order to apply to spintronics technology these spin junction models, we constructed a dual control theory by pseudo-spin quantum Hall effect.
