Next-generation magnetic memory material records with light, not current
Researchers have developed a next-generation magnetic memory material that can write information using light rather than electric current. The team expects the technology to enable data writing up to 1,000 times faster than existing magnetic memory while using less power. The material uses an optical switching phenomenon that flips electron spins with laser pulses. The group combined layered materials to achieve both optical switching and stability, and sees potential uses in AI, data centres and next-generation information processing systems.
