Background
Spin electronics, or spintronics, leverages the quantum property of electron spin, which is an intrinsic form of angular momentum. In traditional electronics, devices rely solely on the charge of electrons, but by also using spin, researchers can create components that are faster and more efficient. The orbital Hall effect, unrelated to the spin-orbit coupling, plays a key role in generating these orbital currents that are harnessed in the study.
History
The field of spintronics first gained traction in the late 20th century with the discovery of giant magnetoresistance, which revolutionized data storage technologies. Since then, researchers have been exploring ways to integrate spin-based mechanisms into electronic devices to enhance efficiency. This latest research builds on the foundation of those earlier studies, specifically focusing on the integration of orbital currents in device architecture.
