"combines ferromagnetism/ antiferromagnetism... 2D nickel iodide crystals at 60°K where spins on nickel atoms form spiral-like configurations that are spin switchable applying small electric field... orders magnitude more data packs onto device... electron’s spin initial direction correlated to handedness of light used to excite... saves 5 orders magnitude of energy... future: finding a material with these properties, at room temperature... then we can apply this to a spintronic device"
