Scientists at Brown University have achieved a major materials science breakthrough by inducing altermagnetic behavior inside an exceptionally thin multiferroic film, paving the way for faster, ultra-dense, and dramatically more energy-efficient AI computer chips. Traditional ferromagnets produce strong electrical readouts but suffer from slow switching speeds and stray magnetic interference, while antiferromagnets operate rapidly without stray fields yet remain difficult to read. Altermagnets combine the best of both worlds—delivering high-speed switching, dense component packing, and clear electrical readout signals that could transform low-power memory hardware.
