Abstract
<p>Since electron spin has a magnetic moment and interacts with the magnetic field through the Zeeman effect, it has been conventionally controlled by external magnetic fields such as for electron spin resonance. Spin-orbit interaction is a relativistic effect that converts an electric field into a magnetic field, and electron spins feel an effective magnetic field dependent on the direction of motion by moving in the electric field. In addition, spin angular momentum and orbital angular momentum are coupled by spin-orbit interaction, and spin up and down electrons are deflected in opposite directions by the spin Hall effect. These features in spin-orbit interaction allow various spin functions based on electrical means without using an external magnetic field. This report reviews the origins of various spin-orbit interactions and their spin-related properties and functions.</p>
