Unlocking Antiferromagnets: A Revolutionary Approach to Computer Memory

Scientists at Nanyang Technological University, Singapore have made a breakthrough in reading data stored in antiferromagnetic materials, which could be used as an alternative to traditional silicon-based computer memory chips. By passing a current through the antiferromagnets at ultra-low temperatures, researchers were able to measure a unique voltage that indicated whether the material was coded as 1 or 0. This discovery provides a practical method for reading data stored in antiferromagnets, which are potentially more energy efficient and less susceptible to corruption than traditional magnetic materials. The research opens up possibilities for faster and more efficient computer memory in the future.

Controlling Antiferromagnetic Vortices in Van der Waals Materials.

Researchers at the University of Tokyo and the RIKEN Center for Emergent Matter Science have confirmed that a specific non-coplanar antiferromagnetic order characterized by scalar spin chirality could elicit a large and spontaneous topological Hall effect in van der Waals materials. The effect could originate from the scalar spin chirality of the compounds that the team examined, which produce a fictitious magnetic field. This phenomenon enables the electrical readout of the antiferromagnetic domains, and it suggests that non-coplanar antiferromagnets may be utilized as a novel information medium.
