Spin Hall Effect

The Spin Hall Effect is a phenomenon where an electric current flowing through a material causes electrons with opposite spins (a quantum property related to their magnetic moment) to move sideways in opposite directions. This results in a separation of spin-up and spin-down electrons across the material's sides, creating a spin imbalance without requiring a magnetic field. It’s useful in spintronics, where we manipulate electron spins for data storage and electronic devices, offering a way to control spin currents using electric currents alone.
