The best candidate for next-generation magnetic devices—technology that can power, store, sense or transport information—may be, counterintuitively, antiferromagnets. Today, the most widely used ...

Conventional hard disks are based on ferromagnets—materials in which the magnetic dipoles, or spins, associated with each atom all point in the same direction. This alignment gives the material a net ...

Scientists have used light to visualize magnetic domains, and manipulated these regions using an electric field, in a quantum antiferromagnet. This method allows real-time observation of magnetic ...
