Abstract: Historically, spintronics research has focused on conventional materials, such as Fe, Co, and Pt. This research has highlighted phenomena like magnetoresistance and spin-torque. In this talk, I will discuss spintronics research utilizing innovative materials, including topological antiferromagnets such as Mn₃Sn and chiral organic molecules. Specifically, I will present our latest research findings on developing antiferromagnetic spintronic devices [1-3] and on elucidating the principles of chirality-induced spin selectivity (CISS) [4,5].
