EPFL scientists have developed a new perovskite material with unique properties to build next-gen hard drives. As we generate more and more data, we need storage systems, e.g. hard drives, with higher density and efficiency. But this also requires materials whose magnetic properties can be quickly and easily manipulated in order to write and access data on them. EPFL scientists have now developed a perovskite material whose magnetic order can be rapidly changed without disrupting it due to heating.
The lab of Laszló Forró synthesized a ferromagnetic photovoltaic material...
