스핀 확산 이론의 기초 및 적용

Abstract

Spin diffusion theory is widely used to interpret experimental results in the field of spintronics. In this paper, we overview the detailed derivation of spin diffusion equation with emphasizing two main assumptions. We discuss possible misinterpretations when applying the spin diffusion equation to spin-orbit torque experiment, where two assumptions of the spin diffusion theory are not applicable in general.
