Unlocking the Mysteries of the Vector Spin-Orbital Hall Effect in Tight-Binding Systems
Today, scientists have discovered a groundbreaking phenomenon that could revolutionize the way we think about spin-based electronics. The phenomenon, known as the Vectorial Spin-Orbital Hall Effect, is a key to unlocking higher efficiency and lower energy consumption in spintronic devices. This effect was observed in tight-binding numerical simulations of a two-dimensional electron gas in a perpendicular magnetic field. These simulations revealed that when the spin-orbit coupling is strong, electrons with opposite spins move in opposite directions, creating a “spin-orbit current”. This current can be used to switch between spin-based logic states with very low energy consumption. This discovery could pave the way for the development of more energy efficient spintronic technology in the near future.
