United KingdomA German-Japanese research team, including the University of Augsburg, has achieved a major breakthrough by using ultrashort laser pulses to write magnetic information in antiferromagnetic materials without requiring electric currents or magnetic fields. Antiferromagnets are seen as promising for next-generation data storage due to their speed and resistance to external interference, though controlling their magnetic states has previously been challenging. The team's method uses the direction of light propagation rather than polarization to control the magnetic state, enabling optical reading and writing of information. This technique works within the telecommunications wavelength range, making it compatible with current optical networks and potentially allowing faster, more energy-efficient data storage and communication systems. The study was published in the journal Nature Materials.
