MIT physicists have discovered a new magnetic state in an antiferromagnetic material using terahertz light, opening doors to revolutionary memory technologies resistant to magnetic interference.

By fine-tuning light vibrations to the atomic level, they have created a magnetic state that persists beyond immediate effects, hinting at future applications in robust data storage and efficient processing.

Cool.

Antiferromagnets could be incorporated into future memory chips that store and process more data while using less energy and taking up a fraction of the space of existing devices, owing to the stability of magnetic domains.
