Effective gauge field theory of spintronics

量子物理学・ナノサイエンス第105回特別セミナー

概要

Spintronics phenomena are discussed based on the concept of effective gauge field [1]. The effective gauge fields arise from structures of localized spin (magnetization) and couple to spin current of conduction electron. The adiabatic component of the gauge field gives rise to spin Berry's phase, topological Hall effect and spin motive force, while nonadiabatic components are essential for Dzyalosinski-Moriya interaction and dynamic spin pumping effects.
