Chiral excitations in spintronics
WebJan 13, 2024 · Equally interestingly, chiral symmetry breaking in spin dynamics can be a purely geometric effect, arising from, for example, the curvilinear shape of magnetic nanocylinders. From an application perspective, chirality in spin dynamics provides a new dimension when designing future spintronic devices. This Special Issue of Symmetry … WebJun 27, 2024 · Abstract. This review describes a new perspective on the role that electron spin plays in the intermolecular forces between two chiral molecules and between chiral molecules and surfaces. This different role of the spin arises from the chiral induced spin selectivity (CISS) effect which is manifest when electrons are moving in chiral molecules.
