Abstract
Spin is one of the most wonderful and exotic properties of the elementary particle in physics. In the worlds of condensed matter physics and materials physics, spin plays a crucial role in both aspects of fundamental research and application. In this colloquium talk, I will introduce several examples in the fields of nanomagnetism and spintronics, by demonstrating the novel effect of an antiferromagnetic layer on the perpendicular magnetization [1,2] and the transport mechanism of spin-polarized electrons through organic materials [3,4]. A very recent interest on the spin-momentum locked system, such as topological insulator and Rashba-semiconductor will be also addressed, for example, the discovery of a spontaneously formed “Rashba p-n junction” of strongly Rashba-split electrons and holes [5].
