What do you get when you place a thin film of perovskite material used in solar cells on top of a magnetic substrate? More efficient hard drive technology. EPFL physicist László Forró and his team pave the way for the future of data storage.
“The key was to get the technology to work at room temperature,” explains László Forró, EPFL physicist. “We had already known that it was possible to rewrite magnetic spin using light, but you’d have to cool the apparatus to—180 degrees Kelvin.”
