"Efficient Computing with 2D Magnetic Materials"

Researchers at MIT have demonstrated precise control of a van der Waals magnet at room temperature, a significant step towards integrating 2D magnetic materials into functioning computers. By using pulses of electrical current to switch the direction of the device’s magnetization, the team achieved greater energy efficiency and room-temperature switching, paving the way for faster, more energy-efficient computers and nonvolatile magnetic computer memories. The atomically thin iron gallium telluride material used in the experiment has the potential to bring the versatility of van der Waals magnets to commercial applications, with the researchers aiming to achieve switching without the need for any external magnetic fields 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.
