Optical writing of antiferromagnets points toward new storage devices and energy efficient information systems
A German-Japanese research team involving the University of Augsburg has made a significant breakthrough in the use of antiferromagnets. For the first time, the team has succeeded in writing magnetic information using only ultrashort laser pulses-without the need for electric currents or magnetic fields.
The tech section covers stories about technology making life better, not just more profitable. Open-source tools reaching new audiences, accessibility breakthroughs, AI applications in healthcare and education, infrastructure improvements that quietly make cities work better. Product launches and funding rounds are excluded unless they deliver tangible public benefit.
The agency says that they "appear to be pressure vessels from a space launch vehicle".
