Description

Chao Yun and co-authors flip a layered magnet's poles with current alone at room temperature in two thousand twenty-three. Layered van der Waals magnets offer clean surfaces for electrical control of magnetism, prized for future memory and logic. Past demos needed deep cold or a helper magnetic field.

Their stack pairs the magnet Fe3GaTe2, magnetic at room temperature with strong upright alignment, against platinum. Current through the stack twisted the magnet's switching field with high efficiency, then flipped it fully. A shaped, lopsided layout even produced sideways spin currents that flipped the magnet with no field at all. The result clears a path to practical van der Waals spin devices.
